N.B. That in particular does sound like what might sometimes be called
"filtering" or "narrowing" rather than "searching".  Of course, it's
still kind of "searching" (or "finding" ... whatever...)

I presently use some simple ad-hoc code to implement my desired filters
in my application, but I've recently been looking closely at
django-filter which might provide more structure to the implementation:
http://github.com/alex/django-filter

(The other thing I do is use the nice jquery datatables plugin which
provides further last-minute intra-results text search on the client
side - http://www.datatables.net/ )

Re: Which apps/solutions are most appropriate for model based search in Django?

Yes, I am also not convinced that an engine focused on full-text
search is relevant in this case. But i am no expert on that.

I haven't actually benchmarked the performance of the current solution
I am using, I am just looking to get some opinions or solutions if
django users have encountered this scenario before.

I am so tied in to Django models and my searches also return Django
querysets. If I do need to change tracks, I would be looking for some
solution that returns Django models and querysets on search. I am
going through a lot of projects on github and Google code, just
reading through their docs and source.

Given your specs, I don't see the point of fulltext search here.
Unless of course you want to add a more generic search feature (like
typing any random name or word and finding out which students have any
association with this name or word, directly or via related models).

Seems ok to me.

Did you actually benched your current solution with representative
data and load ?

Which apps/solutions are most appropriate for model based search in Django?

[chefsmart]

This is on stackoverflow.com also, but I guess not all Django users
visit that site so I am posting this here also: -

I have a Django app where most of the search is driven by foreign
keys. For example, assuming Student, School, State, and
EducationalQualification are Django models, the user would search for
Students by specifying search criteria by selecting from lists of
Schools, States, Degrees, Diplomas etc. That is, a search on students
is essentially an answer to the question "Show students that belong to
the following schools, and who belong to the following states, and who
have the following degrees / diplomas".

My Django app is purely database driven - there are no documents or
webpages to search.

In this case where searching for Django models are guided mostly by
the foreign keys that model has, what search apps/solutions are most
appropriate? The ones I have taken a look at all talk a lot about full
text search, I may be wrong but I don't think that is appropriate in
my case.

I am currently searching using Peter Herndon's approach (http://
www.slideshare.net/tpherndon/django-search-presentation). But this is
expected to be a high-traffic site and I am worried about speed and
performance.

Regards,
CM.
