We need to implement a search filter (Net-log like) for my social networking site

We need to implement a search filter (Net-log like) for my social networking site against user profile, filters on profile include age range, gender and interests

we have approx 1M profiles running on MySQL, MySQL doesn’t seems the right option to implement such filters so we are looking on Cassandra as well,

So what is the best way to implement such filter, The result need to be very quick

e.g. age = 18 – 24 and gender = male and interest = Football

Age in Date, Gender and interests are varchar

EDITED:

Let me rephrase the problem, How can I get fastest result of any type of search.
It could be on the bases of profile name, or any other profile thing on 1M profile records.

Thanks

    It would serve your project well to make an underlying SQL change. You might want to consider changing the Interest column from a free-input field (varchar) to a tag (Many-to-many on an additional table, for example).

    You used the example of Football and having a like operator on it. If you changed it to a tag, then you will have an initial structural problem of deciding where to place:

    football
Football
American Football
Australian-rules football

    But once you have done so, the tags will help your select statement go much faster.

    Without this change, you will be pushing your data management problem from a database (which is equipped to handle it) to Java (which might not be).
