Hi Francisco,

>> I have many drug products leaflets, each corresponding to 1 product. In
the
other hand we have a medical dictionary with about 10^5 terms.
I want to detect all the occurrences of those terms for any leaflet
document.
Take a look at SolrTextTagger for this use case.
https://github.com/OpenSextant/SolrTextTagger

10^5 entries are not that large, I am using it for much larger dictionaries
at the moment with very good results.

Its a project built (at least originally) by David Smiley, who is also
quite active in this group.
