Sorry for this lengthy post, but I wanted to be complete.
The only occurence of edismax in solrconfig.xml is this one:
<requestHandler name="/scoresearch" class="solr.SearchHandler"
default="true">
<lst name="defaults">
<str name="defType">edismax</str>
<str name="echoParams">explicit</str>
<int name="rows">10</int>
<str name="qf">double_score</str>
<str name="debug">false</str>
<str name="q.alt">*:*</str>
</lst>
</requestHandler>
I don't have a requestHandler named "/select".
Also, removing the gramming definitely helped! :-)
I tried to simplify my setup first and then expand, so what I have now is
this:
<fieldType name="searchtext_nl" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords_nl.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SnowballPorterFilterFactory" language="Kp"
protected="protwords_nl.txt"></filter>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords_nl.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SnowballPorterFilterFactory" language="Kp"
protected="protwords_nl.txt"></filter>
</analyzer>
</fieldType>
<field name="title_search_global" type="searchtext_nl" indexed="true"
stored="true"/>
In my database I have these 4 values for "title" that populate
"title_search_global"
"Hi there dier something else"
"Hi there dieren zaak something else"
"Hi there dierenzaak something else"
"Hi there dierzaak something else"
ps. "dier" is singular of plural "dieren".
Using this query:
http://localhost:8983/solr/search-global/select?q=title_search_global%3A(dieren+zaak)&fq=(lang%3A%22nl%22+OR+lang%3A%22all%22)&fl=id%2Ctitle&wt=xml&indent=true&defType=edismax&qf=title_search_global&stopwords=true&lowercaseOperators=true&debug=true
These results are found:
"Hi there dier something else"
"Hi there dieren zaak something else"
And these are NOT:
"Hi there dierenzaak something else"
"Hi there dierzaak something else"
I'd expect it should be fairly easy (although I don't know how) to also
include result "dierenzaak", by compounding the 2 query values. And yes you
are correct: in Dutch "dieren zaak" would mean the same as "dierenzaak". Not
sure what logic would also include "dierzaak"
Regarding your question: yes, I do consider "dieren zaak soemthingelse" an
exact match of "dieren zaak"
So I also checked the usage of pf parameters with edismax (based on these
links:
https://lucene.apache.org/solr/guide/6_6/the-extended-dismax-query-parser.html,
http://blog.thedigitalgroup.com/vijaym/understanding-phrasequery-and-slop-in-solr/)
And also for dismax:
https://lucene.apache.org/solr/guide/6_6/the-dismax-query-parser.html#TheDisMaxQueryParser-Theqs_QueryPhraseSlop_Parameter
But I can't find any examples how to actually use these parameters?
