MathSearch

This is obsolete, not available

To search a collection of over 200,000 documents on English-language mathematics and statistics servers across the Web, enter one or more ``phrases'', then start the search.

Note that most of the material is concerned with research-level and university mathematics.

Each ``phrase'' should be an (unordered) set of one or more words which you would hope to see occurring together in the same sentence in documents returned by the search. Words you would like to see in the same document but not necessarily in the same sentence should be put in different phrases. It is important that words should be spelt correctly.

It is better to start with a simple broad query, and refine it to a more precise one later if necessary.

Additional details

Words are reduced to a stem by removal of common suffices before searching is performed, so in general you need not worry about singular versus plural and other grammatical distinctions. Overly frequent words and stems are ignored. The search is not case-sensitive.

For each document matched, the following are reported:

• how many sentences in the document contain each phrase
• the document title if it exists (otherwise the URL is given)
• the WWW server containing the document (if not already given in the URL)
• the number of sentences in the document
• the total number of stems, other than the ones ignored, in the document.

There is a partial description of how the index information was collected.
