Certain Plurals Not Working SOLR v3.6

[Sara Woodmansee <sw...@gmail.com>]

Hello all,

We are having a website built with a search engine based on SOLR v3.6.  We submit terms (keywords) as singulars, and the code is supposed to add (search for) plurals.

Most search terms work, but we have an issue with plural terms that end in -ee, -oe, -ie, -ae,  and words that end in -s.  In comparison, the following work fine: words that end with -oo, -ue, -e, -a.

The developers have been unable to find a solution, but this has to be a common issue (?) Someone surely has found a solution to this problem??  I am not a coder, but we are quite desperate to find a solution to this issue, as search absolutely needs to work. Here was the developers feedback: "Unfortunately we tried to apply all the filters for stemming but this problem is not resolved". https://wiki.apache.org/solr/LanguageAnalysis#English

Any suggestions greatly appreciated.

Thanks!
Sara
