For some time I've wondered what the argument might be to use SOSL instead of SOQL. I can't find anything that says it's faster, and it's limited in the field types it can search, and the flexibility of the search results. As far as I've seen every situation that could be contrived as a use-case for SOSL can be done very neatly with SOQL. 

I suppose what I'm trying to say is, can you convince me that sometimes I should be using SOSL?
