Well, are you working with multi-word synonyms? If so, then yes, I'd say
that makes sense to do it at index time. Otherwise, it really depends on
a host of factors.
In terms of your settings, if you expand synonyms at index time, what
would be the point of reducing synonyms at query time? I think you just
need the index time filter?

hi all,
i am confused a bit about how to use synonym filter configs. i am using
solr 1.4.
default config is like :
for query analyzer:
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
for index analyzer:
its commented.
while looking @ documentation deeply on
http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#head-2c461ac74b4ddd82e453dc68fcfc92da77358d46
*"**Keep in mind that while the SynonymFilter will happily work with
synonyms containing multiple words (ie: "**
sea biscuit, sea biscit, seabiscuit**") The recommended approach for
dealing with synonyms like this, is to expand the synonym when indexing. This
is because there are two potential issues that can arrise at query time**"

*
*
considering this above recommendation i think following is the best option
for synonym filter
* for query analyzer: *
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="false"/>
for index analyzer:
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
am i right?
what do you guys suggest?
thanks!
