Sure. You could say the same for gathering identifiers from Ada sources for a search engine for Ada sources. A lexer is ok for that job. Would you conclude that Ada doesn't need to be parsed ?
Or reversely, how would you manage to display HTML lists or tables without a parser ? With a search engine crawler you just throw away the HTML structures. This is okay for your crawler: you just need the text between the tags.
