Chris Williams commented on SOLR-629:
-------------------------------------
Hi,
FYI: the patch didn't seem to apply cleanly on 1.3, but worked fine on 1.4
Anyways, I'm having some trouble with this patch. It doesn't seem to respect
any of my query filters.
For example, I have a dismax query
where q=the game
where qf = 'title_words~.06'
where my 'title_words' field is:
<fieldType name="textExactWSTokenized" class="solr.TextField"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.ISOLatin1AccentFilterFactory"/>
<filter class="solr.StandardFilterFactory"/>
<filter class="solr.TrimFilterFactory" />
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
I get this as the parsed query:
"parsedquery_toString"=>"+(((title_words:the~0.6)~0.01
(title_words:game~0.6)~0.01)~2) ()"
(I don't want it running anything on the word 'the' because its a stop word)
Yet if I change qf to just 'title_words' and remove the fuzziness, same query
text, I get this:
"parsedquery_toString"=>"+(((title_words:game)~0.01)~1) ()"
(which is what I want)
> Fuzzy search with DisMax request handler

> Key: SOLR-629
> URL: https://issues.apache.org/jira/browse/SOLR-629
> Project: Solr
> Issue Type: Improvement
> Affects Versions: 1.3
> Reporter: Guillaume Smet
> Priority: Minor
> Attachments: dismax_fuzzy_query_field.v0.1.diff,
> dismax_fuzzy_query_field.v0.1.diff
>
>
> The DisMax search handler doesn't support fuzzy queries which would be quite
> useful for our usage of Solr and from what I've seen on the list, it's
> something several people would like to have.
> Following this discussion
> http://markmail.org/message/tx6kqr7ga6ponefa#query:solr%20dismax%20fuzzy+page:1+mid:c4pciq6rlr4dwtgm+state:results
> , I added the ability to add fuzzy query field in the qf parameter. I kept
> the patch as conservative as possible.
> The syntax supported is: fieldOne^2.3 fieldTwo~0.3 fieldThree~0.2^-0.4
> fieldFour as discussed in the above thread.
> The recursive query aliasing should work even with fuzzy query fields using a
> very simple rule: the aliased fields inherit the minSimilarity of their
> parent, combined with their own one if they have one.
> Only the qf parameter support this syntax atm. I suppose we should make it
> usable in pf too. Any opinion?
> Comments are very welcome, I'll spend the time needed to put this patch in
> good shape.
> Thanks.
