hi Steve,
thanks for the pointer. this is a Lucene entry... I thought the Latin-filter
was a SOLR feature? I, for one, definitely meant a SOLR filter.
Given what Walter rightly pointed out about differences in language, I suspect
it would be a SOLR-level thing - fieldType name="textDE" language="DE" would
apply the filter of unicode chars to {ascii?} with the appropriate mapping for
German, etc.
Or is this that Lucene would / should take care of ?

List of available facet fields returned with the query results
Hi, I have solr setup to index technical data for a number of different types of products, and this means that different product have different facet fields available. For example here would be a small example of the sort of data we are indexing, in reality there are between 10 and 20 facet fields per product dependent upon its category, but a user could perform a search across more than one category. A typical search would be: Stage 1 1) User types a keyword 2) The matched category's from that search are displayed 3) User chooses a category 4) All results that match that category and keyword are displayed and it's at this point I would like to display the available facets and values. Name: Microsoft Optical Mouse for PC DPI: 1200 Type: Laser Category: PC Price: 45.00 Name: Eee PC Storage Type: Flash Screen Size: 17 Category: Netbook Price: 200.00 And so on. So if I search for "PC" and then category "Netbook" I would like solr to be able to tell me what facet fields are available without me resorting to a database to store which facets fields are available to search for which products, is there any way to get SOLR to return as part of the results a list of the facets available for the current search results or even better could I get it to automatically do a facet query for each of those fields to allow drill down querys. The current commercial tool we use that we are hoping solr can replace is called "FactFinder" and does exactly this, but I do have to have drilled down a number of times before this occurs, to stop the search attempting to return facets for every item in the index. I suspect am I missing a trick here or making this more complicated than needed, any help or ideas much appreciated. Thanks Barry H Misco is a division of Systemax Europe Ltd.

Re: List of available facet fields returned with the query results
Hi Barry, If each category has an exclusive set of fields on which you want to facet on, then you can simply facet on all facet-able fields (across all categories). The ones which are not present for the selected category will show up with zero facets which your front-end can suppress. However if the total number of such fields are very large, you may be better off managing the mappings yourself for performance reasons.

A fair portion of Solr is a set of wrappers over Lucene functionality.
ISOLatin1FilterFactory, for example, wraps Lucene's ISOLatin1AccentFilter.
Here is the entirety of the Solr code:
public class ISOLatin1AccentFilterFactory extends BaseTokenFilterFactory {
public ISOLatin1AccentFilter create(TokenStream input) {
return new ISOLatin1AccentFilter(input);
}
}
Of course, BaseTokenFilterFactory brings more to the party, but my point is
that adding Lucene filters to Solr is generally a trivial exercise - a Solr
...FilterFactory around LUCENE-1343 would not be much longer than the four
lines listed above, since the configuration aspects are already handled by
BaseTokenFilterFactory.

The kind of filter Walter is talking about - a generalized language-aware
character normalization Solr/Lucene filter - does not yet exist. My guess is
that if/when it does materialize, both the Solr and the Lucene projects will
want to have it. Historically, most functionality shared by Solr and Lucene is
eventually hosted by Lucene, since Solr has a Lucene dependency, but not
vice-versa.
So, yes, Solr would be responsible for hosting configuration for such a filter,
but the responsibility for doing something with the configuration would be
Lucene's responsibility, assuming that Lucene would (eventually) host the
filter and Solr would host a factory over the filter.

RE: List of available facet fields returned with the query results
Hi Shalin, As there is certainly the potential for several thousand different attribute types across all of our category's I guess I will have to manage them myself (was hoping for a short-cut or that I was missing a trick) but no problem.

Re: Index size vs. number of documents
Erick Erickson wrote: I'm surprised, as you are, by the non-linearity. Out of curiosity, what is your MaxFieldLength? By default only the first 10,000 tokens are added to a field per document. If you haven't set this higher, that could account for it. We set it to a very large number so we index the entire document. As far as I know, optimization shouldn't really affect the index size if you are not deleting documents, but I'm no expert in that area. I've indexed OCR data and it's no fun for the reasons you cite. We had better results searching if we cleaned the data at index time. By "cleaning" I mean we took out all of the characters that *couldn't* be indexed. What *can't* be indexed depends upon your requirements, but in our case we could just use the low ASCII characters by folding all the accented characters into their low-ascii counterparts because we had no need for native- language support. And we also replaced most non-printing characters with spaces. A legitimate question is whether indexing single characters makes sense (in our case, genealogy, it actually does. Sggghhh) Fortunatel non-printing characters are not a problem but we need native language query support so limiting to US-ASCII will not work for us. One possibility is to identify the dominant language in the document and use dictionaries to remove junk however proper names are a big problem with that approach. Another might be to use heuristics like removing "words" with numbers in the middle of them. Whatever we do wil lhave to be fast. In a mixed-language environment, this provided surprisingly good results given how crude the transformations were. Of course it's totally unacceptable to so mangle non-English text this crudely if you must support native-language searching. yes. I'd be interested in how this changes your index size if you do decide to try it. There's nothing like having somebody else do research for me .

If the index size were a linear function of number of documents, based on just these two data points, you'd expect the index for 174237 docs to be approximately 57.98 times larger that 723 MB or about 41921 MB. Actually it's 51460 or about 22% bigger. I suspect the non-linear increase is due to dirty ocr that continually increases the number of unique words that need to be indexed. Another possibility is that the larger index has a higher proportion of documents containing characters from non-Latin alphabets thereby increasing the number of unique words. I can't verify that at this point. Are these reasonable assumptions or am I missing other factors that could contribute to the non-linear growth in index size? Regards, Phil

More files in index directory than expected
It's my understanding that if my mergeFactor is 10, then there shouldn't be more than 11 segments in my index directory (10 segments, plus an additional segment if a merge is in progress). It would seem to follow that there shouldn't be more than 11 fdt files, 11 tis files, etc.. However, I'm looking at one of my indexes now, and this doesn't seem to be the case. Here are the tis files for this index, for instance: 07/22/2008 07:49 PM77,925,180 _1je.tis 07/23/2008 02:57 AM65,988,651 _256.tis 07/23/2008 04:18 AM13,159,578 _29t.tis 07/23/2008 05:08 AM10,146,941 _2cw.tis 07/23/2008 05:39 AM 6,749,665 _2el.tis 07/23/2008 06:24 AM12,274,012 _2he.tis 07/23/2008 07:01 AM14,069,531 _2kh.tis 07/23/2008 07:53 AM13,795,213 _2nu.tis 07/23/2008 08:20 AM 6,284,902 _2p0.tis 07/23/2008 08:27 AM 1,980,945 _2p9.tis 07/23/2008 08:36 AM 1,674,640 _2pk.tis 07/23/2008 08:37 AM 311,483 _2pl.tis 07/23/2008 08:38 AM 285,881 _2pm.tis 07/23/2008 08:39 AM 245,138 _2pn.tis 07/23/2008 08:40 AM 116,881 _2po.tis 07/17/2008 11:22 PM69,635,905 _rp.tis 07/18/2008 12:59 AM15,883,866 _xu.tis There are 17 of these files. (File sizes are in bytes.) When I open up the index in Luke, it says all of them are "In Use" and it doesn't list any of them as "Deletable". This seems to rule out the possibility that Solr/Lucene somehow "forget" to clean up files that were no longer in use. I'm noticing that _2pk, _2pl, _2pm, _2pn, _2po are sequential file names, alphabetically speaking, and their last modified times are very close to one another. Does this mean they're actually part of the same segment, even though they are in separate files? If those files are indeed part of a single segment, then the number of segments represented by these files would really be 17-4=13. But that's still more than the expected 11 segments. I just discovered that one of my other indexes has over 11,000 tis files. That's disturbing. I'm not sure if it would have the same underlying cause. Any ideas?

IndexOutOfBoundsException
Hi, I have rebuilt my index a few times (it should get up to about 4 Million but around 1 Million it starts to fall apart).

Highlighting returns incorrect text on some results?
This is kind of a strange issue, but when I submit a query and ask for highlighting back, sometimes the highlighted text includes a question mark at the beginning, although a question mark character does not appear in the field that the highlighted text is taken from. I've put some sample XML output on the web at http://ucair.cs.uiuc.edu/pdovyda2/problem.xml If you look at the first and third highlights, you'll see what I'm talking about. Besides looking a bit odd, it is causing my application to break because the highlighted field is multivalued, and I was doing text matching to determine which of the values was chosen for highlighting. Is this actually a bug, or have I just misconfigured something? By the way, I am using the 1.2 release, I have not yet tried out a nightly build to see if this is an old problem.

Re: term list
Assuming you mean significant in the traditional IR sense, I would start with the MoreLikeThis. See http://wiki.apache.org/solr/MoreLikeThisHandler In particular the mlt.interestingTerms option. As for phrases, that is a bit harder. You could try playing around with token-based n-grams (called Shingles) and MoreLikeThis together, for starters, I think. If you have some other notion of "significant" in relation to language in general, then you've got quite a bit more work to do, most of which is way beyond the scope of Solr (although it could plugin to Solr nicely).

QueryResultsCache and DocSet filter
We have a bunch of user caches that return DocSet objects. So, we intersect them and send a DocSet filter and the actual query to getDocListAndSet or getDocList. The problem here is that the calls in SolrIndexSearcher don't appear to use the QueryResultsCache if the filer is a DocSet rather than a List. So, the end result is that our new version of Solr is slower than our old version. Our old version cached Query objects instead of DocSets. However, it had quite a few other problems. I thought it would be an improvement to use DocSets. Is it recomended to re-work the caches to return Query objects and use that as my filterList? Our index size is about million documents. Our typical result set size is about 15, but can occasionally be in the range of 5,000-15,000.
NOTICE - solrj MultiCore{Params/Request/Response} have been renamed CoreAdmin{Params/Request/Response}
In the effort to clean up confusion around MultiCore usage, we have renamed the class that handle runtime core administration from "MultiCoreX" to CoreAdminX. Additionally, the path that the default MultiCoreRequest expects to hit is: /admin/cores rather then /admin/ multicore -- if you have an existing solr.xml file, you may want to update the "adminPath" attribute for a detailed change log, see: http://svn.apache.org/viewvc?view=rev&revision=685989 ryan

Actually, mergeFactor 10 means each *level* will have <= 10 segments, where a level is roughly 10X the size of the previous level. EG after 10 segments (level 0) are flushed, they get merged into a single level 1 segment. Another 10 produces another level 1 segment. Etc.

Re: QueryResultsCache and DocSet filter
The DocSet isn't part of the cache key. The key is usually just a simple string (e.g. companyId). They just return a DocSet. I think the user caches are fine. This DocSet is then used as a filter for the actual query. I believe it is this step that is slow. However, I am guessing that the solution is still to have the user caches return a Query object so that I can supply a List to SolrIndexSearcher, causing it to use the QueryResultsCache.

Simple Searching Question
Hello, I inserted the following documents into Solr: --- 124 Jake Conk 125 Jake Conk --- id is the only required integer field. foobar_facet is a dynamic string field. When I try to search for anything with the word Jake in it the following ways I get no results. select?q=Jake select?q=Jake* I thought one of those two should work but the only way I got it to work was by specifying which field "Jake" is in along with a wild card. select?q=foobar_facet:Jake* 1) Does this mean for each field I would like to search if Jake exists I would have to add each field like I did above to the query? 2) How would I search if I want to find the name Jake anywhere in the string? The documentation (http://lucene.apache.org/java/docs/queryparsersyntax.html) states that I cannot use a wildcard as the first character such as *Jake* Thanks, - Jake

Thanks, that undoes a lot of my confusion.
As for segment creation, is it accurate to say the following: Solr
will write a new level 0 segment to disk each time an additional
ramBufferSizeMB (default=32MB) worth of data have been added to the
index. Furthermore, once that 32MB worth of data has been written to
disk, those segment's files will never be modified. (The only time a
segment will be modified is if you delete files from it, and that will
only alter the segment's .del file, leaving .tis and friends alone.)

I don't know exactly what happened, but I restarted Solr once or twice
and then when I started adding documents again, Solr started deleting
segment files, and brought things down from like 500GB to like 18GB. I
feel like I read somewhere that Solr sometimes has trouble deleting
segment files when running on Windows. (I'm on Windows right now.) I
wonder if that's related.
The main thing that bugs me about this index now is that the latest
version of Luke (0.8.1) won't open it. ("Unknown format version: -6")
The Solr Luke handler works fine with it, though.

Luke comes with a released version of Lucene probably, while solr is
using a later version. You have to start luke with the solr Lucene jar
on the classpath. There are directions to do this type of thing on the

Right... file deletion just tends to be delayed a bit longer on Windows. For example, if you do an optimize, all the segments will be merged into a single segment, but because a reader is still holding open the old index, you will see both sets of files. The old set of files will be deleted when a new IndexWriter is opened after the old reader is closed. -Yonik

you're likely not copyField-ing *_facet to text, and we'd need to see what type of field it is to see how it will be analyzed at both search/index time. the default schema.xml file is pretty well documented, so you might want to spend some time looking thru it, and reading the commentslots of good info in there. cheers, rob On Thu, Aug 14, 2008 at 7:17 PM, Jake Conk <[EMAIL PROTECTED]> wrote: > Hi Shalin, > > "foobar_facet" is a dynamic field.

Re: Index size vs. number of documents
: > I'm surprised, as you are, by the non-linearity. Out of curiosity, what is Unless the data in "stored" fields is significantly greater then "indexed" fields the Index size almost never grows linearly with the number of documents -- it's the number of unique terms that tends to primarily influence the size of the index. At some point someone on the java-user list who really understood the file formats wrote a really great forumla for estimating the size of the index assuming some ratios of unique terms per doc, but i can't find it now. -Hoss
