i am not very sure, whether this helps me.
i see the point, that there will be problems.
but
the default-config for index is:
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="1"
generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0"
splitOnCaseChange="1"/>
and for query:
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="0"
generateNumberParts="0" catenateWords="0" catenateNumbers="0" catenateAll="0"/>
with this settings i don't find "profiauskunft" when searching for
"profi-auskunft" (analyse0.jpg)
if i use "catenateWords="1""
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="0"
generateNumberParts="0" catenateWords="1" catenateNumbers="0" catenateAll="0"/>
analysis.jsp says that there is a match (analyse1.jpg).
but in our life search "profi-auskunft" won't match "profiaukunft", only finds
"profi-auskunft".
could anyone please clearify the output of analysis.jsp for me.
why is there a highlight in anylises.jsp but not a match when doing a search.
even from the admin panel
when i have
profi auskunft
profiauskunft
does this mean "profi (auskunft profiauksunft)" will match the word "profi"
follewed by "auskunft" or "profiauksunft".
is this OR the same as i configure with defaultOperator in solrQueryParser-tag?
the "OR"-thing does only apply to the query-part, right? what will that mean in
the index part?
