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!
