Hello,
I have confronted with strange behavior of the Solr search and I have no idea
how to fix it.
Version:
* solr-spec 4.3.0
* solr-impl 4.3.0 1477023 - simonw - 2013-04-29 15:10:12
* lucene-spec 4.3.0
* lucene-impl 4.3.0 1477023 - simonw - 2013-04-29 14:55:14
There is field in schema:
<field name="global_name" type="text_general_ngrammed" indexed="true"
stored="true" />
<fieldType name="text_general_ngrammed" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="1"
generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="1"
splitOnCaseChange="1" preserveOriginal="1"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.NGramFilterFactory" minGramSize="1"
maxGramSize="30" />
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="1"
generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="1"
splitOnCaseChange="1" preserveOriginal="1"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
Also there is a record with global_name = "Hong Kong Forever Fame Industrial
Limited"
When I make search with query like:
select?q=global_name:(((hung~1+OR+hung^1.2)+(kong~1+OR+kong^1.2)+(forever~2+OR+forever^1.2)+(fame~1+OR+fame^1.2)+(industrial~2+OR+industrial^1.2)))&start=0&rows=10&q.op=AND&version=2.2
select?q=global_name:(((hqng~1+OR+hqng^1.2)+(kong~1+OR+kong^1.2)+(forever~2+OR+forever^1.2)+(fame~1+OR+fame^1.2)+(industrial~2+OR+industrial^1.2)))&start=0&rows=10&q.op=AND&version=2.2
select?q=global_name:(((hrng~1+OR+hrng^1.2)+(kong~1+OR+kong^1.2)+(forever~2+OR+forever^1.2)+(fame~1+OR+fame^1.2)+(industrial~2+OR+industrial^1.2)))&start=0&rows=10&q.op=AND&version=2.2
...
I get the expected result: record for "Hong Kong Forever Fame Industrial
Limited".
However, for some query:
select?q=global_name:(((hing~1+OR+hing^1.2)+(kong~1+OR+kong^1.2)+(forever~2+OR+forever^1.2)+(fame~1+OR+fame^1.2)+(industrial~2+OR+industrial^1.2)))&start=0&rows=10&q.op=AND&version=2.2
select?q=global_name:(((heng~1+OR+heng^1.2)+(kong~1+OR+kong^1.2)+(forever~2+OR+forever^1.2)+(fame~1+OR+fame^1.2)+(industrial~2+OR+industrial^1.2)))&start=0&rows=10&q.op=AND&version=2.2
...
The result is empty.
It looks like the result depends on letter which user write instead of "o" in
"hong".
I observe such behavior if there are a lot of records (about 94k) which is
expected amount. When there is only one record(case for testing) for "Hong Kong
Forever Fame Industrial Limited" everything works OK.
I would be grateful if you could suggest how to fix this problem.
