There is a French company called Pertimm which develops a search engine that does this with documents. It even does cross-language queries based on sophistocated linguistic analysis. Often, I wish google had some of those features, if even a primitive synonym table.
The relevance here, though, is that the Pertimm index is much larger than the actual text that be being indexed. That's not a problem, really, because the same is true for google. You need that for efficient searches. But there is no place for such a thing in a file system. I don't think any Linux developers would want the metadata to even APPROACH the size of the file data, let alone get LARGER.
Indexing of this sort has its place, but applying it to a whole file system is much too broad of a use. For instance, you wouldn't want to index the contents of your binary programs, or even shell scripts for that matter. So text, data, and code need to have different kinds of indexing.
