Query on date fields
Hi, I have two date attributes in my Indexes: DisplayStartDate_dt DisplayEndDate_dt I need to fetch results where today's date lies between displayStartDate and dislayEndDate. However i cannot send hardcoded displayStartdate and displayEndDate date in query as there are 1000 different dates in indexes Please suggest the query.

How to make wordDelimiterFilter[pulled from Solr nighly] to not break non-english words in a wrong way in lucene indexing/searching?
Hi All,
I'm trying to index some indian web page content which are basically a mix
of indian and say 5% of english content in the same page itself. For all
this I can not use standard or simple analyzer as they break the non-english
words in a wrong places say[because the isLetter(ch) happens to be false for
them, even if they are part of a word]. So I wrote/extended the anayzer that
does the following,
public class IndicAnalyzer extends Analyzer {
public TokenStream tokenStream(String fieldName, Reader reader) {
TokenStream ts = new WhitespaceTokenizer(reader);
//ts = new WordDelimiterFilter(ts, 1, 1, 1, 1, 0);
ts = new StopFilter(ts, StopAnalyzer.ENGLISH_STOP_WORDS);
ts = new LowerCaseFilter(ts);
ts = new PorterStemFilter(ts);
return ts;
}
}
This is working fine to some extent when the line commented above is left as
such, but its not able to give me the results when the documtnt contains a
string say "he...@how.com" and the searched query is hello, this is expected
as the above code doesnot do any word delimiting around these basic
characters [like @ . , etc ].
Now the problem is when I'm trying to use wordDelimiterFilter[hte commented
out line, this filter I got from solr] it is breaking say hindi words around
some characters which are actually part of a word. After going through the
code for this filter I found that it is using the isLetter() standard
fuction of java which I think returns false for those hindi characters
around which it is breaking the words. As per javadoc isLetter() is Unicode
compliant, right? so can't we say that it is aware of the above characters
that they are word delimiters, then why is this breaking around those
characters. I'm stuck and dont know how to get rid of the problem. And
because of this problem when I search for say a hindi word "helo" , assuming
its hindi, it highlights this word but alognwith that it also highlights the
letters of this word h/e/l/o whereever it finds it which it should not do,
right?
I request both Solr and Lucene users to guide me in fixing this issue. BTW,
do we need to do some sort of normalization for the content before sending
it to lucene indexer? just a thought, i don know whats the way out?

Re: Terms Component
It seems like your /terms handler is likely expecting a q parameter due to the QueryComponent being one of the Handlers SearchComponents.

My experience is that it is simple as that: you have to configure something which, in ActiveMath, we have called the "advertizedURL". Making it non-configurable really often creates issues and requires the deployer to dig deep into the servlet container configuration (I never was fully able with mod_proxy and tomcat).

StreamingUpdateSolrServer recommendations?
Hi all, I guess this questions i mainly aimed to you, Ryan. I've been trying out your StreamingUpdateSolrServer implementation for indexin, and clearly see the improvements in indexing-times compared to the CommonsHttpSolrServer :) Great work! My question is, do you have any recommendations as to what values I should use / have you found a "sweet-spot"? What are the trade-offs? Thread count is obvious with regard to the number of cpus available, but what about the queue size? Any thoughts? I tried 20 / 3 as you have posted in the issue thread, and get averages of about 80 documents / sec (and I have not optimized the document processing etc, which takes the larger part of the time). Anyways, I was just curious on what others are using (and what times you are getting at) Keep up the good work! Aleks -- Aleksander M.

Re: solr distributed search example - exception
That is a very odd cast exception to get. Do you want to open a JIRA issue for this? It looks like an odd exception because the call is: NodeList nodes = (NodeList)solrConfig.evaluate(configPath, XPathConstants.NODESET); // cast exception is we get an ArrayList rather than NodeList Which leads to: Object o = xpath.evaluate(xstr, doc, type); where type = XPathConstants.NODESET So you get back an Object based on the XPathConstant passed. There does not appear to be a value that would return an ArrayList. Using XPathConstants.NODESET gets you a NodeList according to the XPath API.

Regarding being able to search SCHOLKOPF (o with no umlaut) and match SCHÖLKOPF (with umlaut) try using the ISOLatin1AccentFilterFactory in your analysis chain: This filter removes accented chars and replaces them with non-accented versions.

Example folder - can we change it?
When I install solr , by default it will install it under /opt/apache-solr-1.3.0/ The bin , config file and data is under /opt/apache-solr-1.3.0/example/solr Is there anyway that we change the example to something else? Because "example" is can be interpreted wrong ( like sample, so it's not real) Francis

Trie Patches- Backportable?
Hi, I am still using Solr 1.2 with the Lucene 2.2 that came with that version of Solr. I am interested in taking advantage of the trie filtering to alleviate some performance problems and was wondering how back-portable these patches are? I am also trying to understand how the Trie algorithm cuts down the number of term queries compared to a normal range query. I was at the recent Bay Area lucene/solr meetup where this was covered but missed some of the details. I know the ideal case is to upgrade to a newer Solr/Lucene but we are resource constrained and can't devote the time right now to test and upgrade our production systems to a newer Solr. Thanks! Amit
Re: searchcomponent howto ...
sorry. my 'tab' character is linked to 'send'. i meant to include this bit
of source
@Override
public void process(ResponseBuilder rb) throws IOException {
SolrQueryRequest request = rb.req;
SolrParams params = request.getParams();
String qs = rb.getQueryString();
String defType = params.get(QueryParsing.DEFTYPE);
defType = defType==null ? QParserPlugin.DEFAULT_QTYPE :
defType;
try {
QParser parser =
QParser.getParser(encoder.process(rb.getQueryString()), defType, request);
rb.setQuery( parser.getQuery() );
rb.setQparser(parser);
} catch (ParseException e) {
throw new
SolrException(SolrException.ErrorCode.BAD_REQUEST, e);
}
}
and then ask,
- how can i set the value of query so that it is reflected in the 'q'
node of the search results e.g. solr.
the example 'process' method above works, but the original query is still
written to the search results page.

Re: Use the same SQL Field in Dataimporthandler twice?
Thanks for your answer.
"${db.tableA.id}" that specifies the sql query that the Dataimporthandler
should Use the sql field "id" in table "tableA" located in Database "db".
like in the example from the Solr Wiki:
"
"
It´s strange I know but when I use something other than "id" as the foreign
key for the query everything works!
like:
"${db.tableA.anotherid}"

Query faceting
Hi, I have a field called "service" with following values: - Shuttle Services - Senior Discounts - Laundry Rooms - ... When I conduct query with "facet=true&facet.field=service&facet.limit=-1", I get something like this back: - shuttle 2 - service 3 - senior 0 - laundry 0 - room 3 - ... Questions: - How not to break up fields values in words, so I can get something like "Shuttle Services 2" back? - How to tell Solr not to return facet with 0 value? The query takes long time to finish, seemingly because of the long list of items with 0 count. thanks for any advice. _ Insert movie times and more without leaving Hotmail®. http://windowslive.com/Tutorial/Hotmail/QuickAdd?ocid=TXT_TAGLM_WL_HM_Tutorial_QuickAdd_062009
Re: Query faceting
In order to get the the values you want for the service field you will need to change the fieldType definition in schema.xml for "service" to use something that doesn't alter your original values. Try the "string" fieldType to start and look at the fieldType definition for "string". I'm guessing you have it set to "text" or something else with a chain of filters during analysis. If you don't want back facets with a count of 0 set this param: &facet.mincount=1 Have a look at all the values you can set on facets: http://wiki.apache.org/solr/SimpleFacetParameters -Jay On Mon, Jun 8, 2009 at 2:09 PM, siping liu wrote: > > Hi, > > I have a field called "service" with following values: > > - Shuttle Services > - Senior Discounts > - Laundry Rooms > > - ... > > > > When I conduct query with "facet=true&facet.field=service&facet.limit=-1", > I get something like this back: > > - shuttle 2 > > - service 3 > > - senior 0 > > - laundry 0 > > - room 3 > > - ... > > > > Questions: > > - How not to break up fields values in words, so I can get something like > "Shuttle Services 2" back? > > - How to tell Solr not to return facet with 0 value?

User Credentials for Solr Data Dir
Hi, I am currently using solr 1.3 and runnign the sole as NT service. I need to store data indexes on a Remote Filer machine. the Filer needs user credentials inorder to access the same.. Is there a solr configuration which I can use to pass these credentials? I was reading some blogs and they suggested to run the NT service with user who can access the resource needed. Since I need to use existing build and deploy tools in the company, and they always run the NT serviec "LOCAL System" which cannot access other resource. Thats why i am trying to explore if its possible to pass these credentials via JNDI/System variables? Is it possible? Thanks Vaibhav _ More than messages–check out the rest of the Windows Live™. http://www.microsoft.com/india/windows/windowslive/
Schema vs Dynamic Fields
On the wiki, it says: > One of the powerful features of Lucene is that you don't have to > pre-define every field when you first create your index. Even though > Solr provides strong datatyping for fields, it still preserves that > flexibility using "Dynamic Fields". Is the use of a predefined schema primarily a "type safety" feature? We're considering using Solr for a data set that is very free-form; will we get much slower results if the majority of our data is in a dynamic field such as: I'm a little unclear on the trade-offs involved and would appreciate a hint.

Re: Collapse Results
both CollapseComponent and QueryComponent
execute searches and add results to the Response.
To get only Collapse results, remove the QueryComponent from the
requestHandler.

The naming convention does not work like that.
if the entity name is 'tableA' then the field 'id' is addressed as 'tableA.id'
As I said earlier, if you could privide mw with the entire
data-config.xml it would be more helpful

Solr relevancy score - conversion
Hi, I am using solr to inxdex some of the legal documents, where i need the solr search engine to return relevancy ranking score for each search results. As of now i am getting score like 3.12, 1.23, 0.23 so on. Would need an more proportionate score like rounded to 100% (95% relevant, 80 % relevant and so on). Is there a way to make solr returns such scores of such relevance. Any other approach to arrive at this scores also be appreciated thanks vijay -- View this message in context: http://www.nabble.com/Solr-relevancy-score---conversion-tp23936413p23936413.html Sent from the Solr - User mailing list archive at Nabble.com.
spellcheck /too many open files
Hi , 1)Does the spell check component support all languages? 2) I have a scnenario where i have abt 20 webapps in a single container.We get too many open files at index time /while restarting tomcat. The mergefactor is at default. If i reduce the merge factor to 2 and optimize the index ,will the open files be closed automatically or would i have to reindex to close the open files or how do i close the already opened files.This is on linux with solr 1.3 and tomcat 5.5 Regards Revas
