Perhaps; I've never been thrilled with strip_tags(), but it should work well enough here. But combined with grep? I guess for most searches grep would narrow things down reasonably well before you have to start processing files in PHP. It would definitely only be useful for a small site (as you suggested). Identifying keywords wouldn't be all that difficult using the OP's method either. The script could easily count the number of occurrences of each word and create an index with the word, the URL, and the number of occurrences (even excluding a list of noise words if desired) without someone having to manually define a list of keywords. It could be run as often as needed to keep the index up-to-date. However, the thing I like most about using FULLTEXT or something like htdig is that they already provide a good combination of indexing and advanced search operators.
