[pmwiki-users] Search for several words with OR operator

[Petko Yotov]

With PmWiki 2.3.26, it should now be possible to enable search of at 
least one item from the search box. Add to config.php:

   $EnableSearchAtLeastOneTerm = 1;

See the documentation. In such a case, to require some terms, precede 
them with "+" such as +term1 +term2.

With this variable enabled, if you're using the snippet I suggested 
earlier, you could replace it with this, it should be about 3 times 
faster:

    $list = [];
    $opt = [''=>['word1', 'word2', 'word3'] ];
    FPLTemplatePageList($pagename, $list, $opt);
    # now $list has all pages that contain word1 OR word2 OR word3

(To require terms, you'd have something like:

    $opt = [''=>['at', 'least', 'one'], '+'=>['required1', 'required2'] 
];
)
