Hoss Man resolved SOLR-3127.
----------------------------
Resolution: Not A Problem
resolving since the issue here just seems to be a missunderstanding of how
dismax works.
if you have questions about this, please start a thread on solr-user. if you
have specific suggestions for how to change dismax to work better in situations
like yours (w/o breaking existing usecases obviously) or suggestions on
improving the documentation then by all means: please open a new issue with
your suggestions
> Dismax to honor the KeywordTokenizerFactory when querying with multi word
> strings
> ---------------------------------------------------------------------------------
>
> Key: SOLR-3127
> URL: https://issues.apache.org/jira/browse/SOLR-3127
> Project: Solr
> Issue Type: Improvement
> Components: query parsers
> Affects Versions: 3.5
> Reporter: Zac Smith
> Priority: Minor
> Labels: dismax
>
> When using the KeywordTokenizerFactory with a multi word search string, the
> dismax query created is not very useful. Although the query analzyer doesn't
> tokenize the search input, each word of the input is include in the search.
> e.g. if searching for 'chicken stock' the dismax query created would be:
> +(DisjunctionMaxQuery((ingredient_synonyms:chicken^0.6)~0.01)
> DisjunctionMaxQuery((ingredient_synonyms:stock^0.6)~0.01))
> DisjunctionMaxQuery((ingredient_synonyms:chicken stock^0.6)~0.01)
> Note that although the query analyzer does not tokenize the term 'chicken
> stock' into 'chicken' and 'stock', they are still included and required in
> the search term.
> I think the query created should be just:
> DisjunctionMaxQuery((ingredient_synonyms:chicken stock)~0.01)
> (or at least not have the individual terms as should match, not must match so
> you could configure with MM.
> Example field type:
> <fieldType name="keyword_test" class="solr.TextField"
> positionIncrementGap="100" autoGeneratePhraseQueries="false">
> <analyzer type="index">
> <tokenizer class="solr.KeywordTokenizerFactory" />
> </analyzer>
> <analyzer type="query">
> <tokenizer class="solr.KeywordTokenizerFactory" />
> </analyzer>
> </fieldType>
