About Searching the JCM

It is possible to perform four different searches over the whole LMS Journal of Computation and Mathematics:

Abstracts

The given terms are searched for just in the abstracts of published papers.

Full Articles

The terms are located anywhere in the article. Page numbers are given for all matches of the search terms.

Titles

Only papers whose title matches the search terms are listed.

Authors

Matches the term in the author list for published papers.

In all cases, the title and authors of matching papers are returned, with the title forming a hyperlink to the given paper.

Stemming

The search engine performs stemming. This means that words with similar stems are considered to be the same for matching purposes. For example, a search term of generator will be considered to have a stem of gener, and so will match generated, generators and general as well as generator. The stem used for matching is highlighted in bold and red in the HTML. To suppress this behaviour, use the Exact button, as described below.

Search terms

A simple boolean syntax is provided, with brackets ``()'' providing grouping, ampersands ``&'' forming a logical AND, and vertical bars ``|'' forming a logical OR.

By default the search engine is case insensitive, and space separated terms are considered to be AND-ed together.

To match an a set of AND-ed terms, each of the terms must be found somewhere in the abstract, title, author list or full article. However, for full articles, the terms must also appear in the same paragraph.

For OR-ed terms, it is sufficient for just one of the to match.

Some examples :

The Exact Button

If the Exact button is depressed, then the given string must be matched exactly; thus, a search term of Queen Victoria will not match any of

• A Queen called Victoria
• Was Victoria a Queen ?
• queen Victoria

Care must be taken when using exact searches on titles, since titles will have various words capitalised.

Also note that brackets, vertical bars and ampersands are treated just as normal characters during an exact search.
