Gert,we're doing a similar process on i2geo search, including simple language expansion (one word is queried in several fields of each language), and, though I haven't made it yet but will soon, I've been suggested to do it as qparser plugin.

[Sorry, post submitted as HTML. Proper format below;]We would like to support concept expansion in searches, i.e. when a user searches for 'software' then the system should also search for keywords / phrases such as program, computer , system, package and class.I imagine that the right way of doing this is a request handler, which expands a query into its conceptual similar entries and aggregates the results. A simple change in the filter from;q:software => q:software OR program OR computer OR system OR package would most likely do the job.Does such a request handler already exist (... looking at the list on the wiki and in the javadocs the answer seems to be no, but maybe its maintained externally)?And is this the right way to go at all? Thanks, Gert.
