Jason Gerlowski commented on SOLR-7981:
---------------------------------------
Ah, I see.
The "newdev" label is actually what initially brought me to this story a while
back! I do share a bit of your frustration that many of the items in the
"newdev" list are already closed, outdated, etc. It's not as easy as it should
be to find approachable tasks that developers can pick up to learn the process.
I'll look around a little bit today and see if I know of anything that's
{{newdev}} appropriate. If I come up with anything I'll let you know.

> The following functions all take exactly 2 arguments: a field name, and a
> term value...
> * idf
> * termfreq
> * tf
> * totaltermfreq
> ...we should consider adding an optional third argument to indicate if an
> analyzer for the specified field should be used on the input to find the real
> "Term" to consider.
> For example, the following might all result in equivilent numeric values for
> all docs assuming simple plural stemming and lowercasing...
> {noformat}
> termfreq(foo_t,'Bicycles',query) // use the query analyzer for field foo_t on
> input Bicycles
> termfreq(foo_t,'Bicycles',index) // use the index analyzer for field foo_t on
> input Bicycles
> termfreq(foo_t,'bicycle',none) // no analyzer used to construct Term
> termfreq(foo_t,'bicycle') // legacy 2 arg syntax, same as 'none'
> {noformat}
> (Special error checking needed if analyzer creates more then one term for the
> given input string)
