For more advanced searching, or to change the output format, use
the selection boxes below, enter the phrase above, and press 'Search'.
Use the 'Match' box to tell the search engine how to interpret the
text you have typed into the box. 'All' looks for all the words you
have typed and will generate a match if all of them are present in the
document. 'Any' will generate a match if any of the words are found.
'Boolean' allows you to specify a 'boolean' statement, using 'and',
'or' or 'not' to generate a possibly complex search statement.
The format allows you to present results in either 'short' format,
showing just the titles, or 'long' showing excerpts from the document.
