Each search term may be preceded by not, and, or or to refine your search. If you search for "Delray Center not red", you'll find all documents containing the word "Delray Center" but not those documents which also contain the word "red". If you type in "and Delray Center and red and green", you'll find only those documents which contain all three search terms. The default value is or. Thus, a search for "Delray Center red green" would return pages with at least one of the three terms.

If a search term has at least one capital letter, like "BLue", the search will be case sensitive - that is, only documents containing "BLue" will be found. On the other hand, lowercase words like "blue" will generate hits from "Blue", "BLUE", or "BLue".

To search for groups of words, use quotes. For example, the query "Delray Center" (quotes included) would not generate a hit from "Delray Center is fun." Without quotes, the sentence would count.

The search finds words, not strings. A search for "in" would turn up only that word, not "bin", "inside", or "acquaintance".
