OK, thanks everyone. Since this is the only thing this field is used for, I think we'll just reindex without the filters and go from there... Now if only I could just reindex that field! Oh well.

I'm wrong: I saw the punctuation being left in for "m_*" and thought

So as Todd pointed out, underscores are dropped during indexing and
searching.  The limitation you are running into is that things like
prefix and wildcard queries are not analyzed (so the _ won't be
dropped).  You could set up another field for use with wildcard
queries, or you could create separate query and index analyzers for
textTight and set the index analyzer to use a WordDelimiterFilter that
also indexes the original token.

That's strange then. The schema hasn't changed in well over a month, solr's been restarted several times since then to reload synonyms and the whole thing was reindexed just this past week to add in new chinese translations
(the fields were already there but left blank).





I attached the full schema if that helps.

I mean, as far as I can tell, that seems right. I think I'm missing
something here.

The wiki page is awesome though, thank you. The catenateAll option does seem to do what I think it did... but should I perhaps just remove any
kind
of filter or analyzer on this field?  It's really not a big deal if
someone
has to get the dashes and underscores exactly right - it's a worse
problem
if they do get them right, but it still doesn't work (usually they copy
and
paste these from an e-mail or something). Just in general, it's never really critical for someone to search by parts of the filename - except
for
searching with wildcard (that is, stm0810m_* and the like), and it would
be
a lot easier if they didn't have to put spaces where letters change to
numbers & vice versa.

Thanks again for your input.

You may want to take a very close look at what the WordDelimiterFilter is doing. I believe the underscore is dropped entirely during indexing
AND searching as it's not alphanumeric.

The admin analysis page and query debug will help a lot to see what's

Subject: Question about textTight

Hi,

So I've been using the textTight field to hold filenames, and I've run into a weird problem. Basically, people want to search by part of a filename (say, the filename is stm0810m_ws_001ftws and they want to
find everything starting with stm0810m_ (stm0810m_*).  I'm hoping
someone might have done this before (I bet someone has).

Lots of things work - you can search for stm0810m_ws_001ftws and get a result, or (stm 0810 m*), or various other combinations. What does not work, is searching for (stm0810m_*) or (stm 0810 m_*) or anything like that - a problem, because often they don't want things with ma_
or mx_, but just m_.  It's almost like underscores just break
everything, escaping them does nothing.

Here's the field definition (it should be what came with my solr):

<fieldType name="textTight" class="solr.TextField"
positionIncrementGap="100" >
  <analyzer>
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt" ignoreCase="true" expand="false"/>
    <filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
    <filter class="solr.WordDelimiterFilterFactory"
generateWordParts="0" generateNumberParts="0" catenateWords="1"
catenateNumbers="1" catenateAll="0"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>
    <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
  </analyzer>
</fieldType>

and usage:

<field name="name" type="textTight"
      indexed="true" stored="true" omitNorms="true"
      />


Now, I thought textTight would be good because it's the one best
suited for SKU's, but I guess I'm wrong. What should I be using for
this?  Would changing any of these "generateWordParts" or
"catenateAll" options help? I can't seem to find any documentation so I'm really not sure what it would do, but reindexing this whole thing will take quite some time so I'd rather know what will actually work
before I just start changing things.

Thanks so much for any insight!
