The fields for which to search. MongoDB's query language is quite
extensive. The PHP driver will in almost all cases pass the query
straight through to the server, so reading the MongoDB core docs on
<link xlink:href="&url.mongodb.dochub.find;">find</link> is a good idea.

<para>
Please make sure that for all special query operaters (starting with
<literal>$</literal>) you use single quotes so that PHP doesn't try to
replace <literal>"$exists"</literal> with the value of the variable
<literal>$exists</literal>.
