We do not use Cassandra for search. We made modifications to Lucene.
Here is a blog post on our engineering section that talks about what we did:

Sasha,
It depends on the way you implement I guess... Maybe twitter uses Solandra,
who's very good at indexing these in different ways but has the power of
Cassandra underneath...
If your doing your own impl of indexing be mindful that you can break the
sentence into four words and index or you i
Why you suppose they did search on Cassandra?

yes -- but given i have two keywords, and want to find all tweets that have
"cassandra" and "bestest" ... means, retrieving all columns + values in
each row, iterating through both to see if tweet id's in one, exist in the
other and finishing up with a consolidated list of tweet id's that only

The simpliest modeling you could have is using the keyword as key, a
timestamp/time UUID as column name and the tweetid as value
-> cf['keyword']['timestamp'] = tweetid
then you do a range query to get all tweetid sorted by time (you may
want them in reverse order) and you can limit to the number
Hi All,
With twitter, when I search for words like: "cassandra is the bestest", 4
tweets will appear, including one i just did. My understand that the
internals of twitter work in that each word in a tweet is allocated,
irrespective of the presence of a # hash tag, and the tweet id is assigned
