Many installations use MediaWiki for applications that are not directly like a dictionary. In such installations, the topic title often describes a topic very accurately, and is often longer than just like a word in a dictionary. One example for such an installation is the Eclipse Wiki, http://wiki.eclipse.org
It would be very helpful to have a substring search capability on the topic title. Our company internal TWiki installation does support such a search.
Other than the fulltext index, topic title substring search should not be restricted to at least 4 characters per word, and should not exclude stopwords. That would make the topic title search a valuable companion to the normal search, improve user experience, and resolve similar issues with 3-character-words and stopwords that have poorly been work-arounded by external searches in the past.
In fact, every default search could show twofold search results: First, all the topic titles that include the search term as substring, and then all the fulltext search matches.
Note that I'm NOT requesting fuzzy matches for topic titles, which seems to have failed in the past. Also note that the Prefix Index is not a suitable workaround, since the search term may not appear as a prefix.
For Eclipse Wiki, see also https://bugs.eclipse.org/bugs/show_bug.cgi?id=214723
In CirrusSearch, there is an "intitle" parameter now (which does not perfectly work yet, see bug 66969).
CirrusSearch is about to replace the default Search, see http://lists.wikimedia.org/pipermail/wikitech-l/2014-July/077375.html
Is that sufficient and what you asked for here?
