Lower case versus capital

For solr, we use http://tartarus.org/martin/PorterStemmer/, with exceptions manually added (e.g don't stem animation and animal to the same word. Porter stems very aggressively, work, works, working, worked all stem to the same root.

On my_uploads, you don't use solr but it should use something close to Porter.

Regarding "If the search is the same I wonder why the Keyword input accepts "Home" and "home" as two different words and counts them as two different words?"

Probably the caching layer got confused and didn't think they the same. Thus in one case you were looking at a cached set and in the next case you forced a new cache generation. When I searched for Home and home just now I got the same results.

And those were the same results I've gotten.

Thanks Marcus, good to know the "ed", "s" and "ing" are not needed, just the root or main word.
Thanks

What about
man men
child children
etc

or man, men, and male ... and possibly "jerk" or "stupid" ... ;)
