Let me briefly explain what I am trying to do. I work on an air gap network. Anything not native to Red hat, or that I do not write is out of the question. The most popular two IDE's are VIM/GVIM and Eclipse.
For many of us, there is only one reason to go into eclipse, the indexer. The code base we work on is quite large. The configuration I work in alone is over a terabyte when compiled. Currently I am using a combination of grep and find to locate files and information in them. It doesn't seem like it should be hard to to write an external indexing deamon, but in order to be useful it would nice to be able to easily interface with a string. I guess I could just copy it to something but I figured I'd check and see if there was some hidden register somewhere that was already doing what I wanted.
