The basic linguistic assumption of proximity searching is that the proximity of the words in a document implies a relationship between the words. Given that authors of documents try to formulate sentences which contain a single idea, or cluster of related ideas within neighboring sentences or organized into paragraphs, there is an inherent, relatively high, probability within the document ...
Nearest neighbor search (NNS), as a form of proximity search, is the optimization problem of finding the point in a given set that is closest (or most similar) to a given point. Closeness is typically expressed in terms of a dissimilarity function: the less similar the objects, the larger the function values.
Intitle does not search redirects. Proximity search is not an option in a title search. To find a match in a redirect title, or to apply a proximity search to a title you can rely on page ranking software to boost title matches before content matches. So a basic word or phrase search, or proximity search, is an alternative to intitle. For example

Proximity, a science fiction drama film; Proximity fuze, a fuze that detonates an explosive device automatically when the distance to the target becomes smaller than a predetermined value; Proximity sensor, a sensor able to detect the presence of nearby objects without any physical contact; Proximity space, or nearness space, in topology
Using an approximate nearest neighbor search algorithm makes k-NN computationally tractable even for large data sets. Many nearest neighbor search algorithms have been proposed over the years; these generally seek to reduce the number of distance evaluations actually performed. k-NN has some strong consistency results.
The search engine supports limited boolean logic in searches. Logical NOT (negation) can be indicated by a "-" (minus sign) or a "!" (exclamation point) character prefixed to a search term, or by the NOT keyword. Parentheses (…) are ignored by the search engine and have no effect. Search terms are implicitly joined by logical AND (conjunction).
