What about the way google does it (i.e. print the surrounding text,
separated by '...' in case of multiple words; for terms appearing
multiple times, I think google just shows the first two or so).
For example, for the search terms "pmwiki php" and the text below:
PmWiki is a WikiWikiWeb clone developed by PatrickMichaud in the PHP
scripting language. PmWiki has been primarily designed as a tool to
support easy, collaborative authoring and maintenance of web sites. PmWiki
is distributed under the General Public License (GPL).
It could print:
"_PmWiki_ is a WikiWikiWeb clone ... in the _PHP_
scripting language... _PmWiki_ has been primarily designed ..."
or even shorter (_word_ means a highlighted word).
