search, forbidden terms, phonetic search, and approximate spelling. Exact
search is what you would expect, i.e., phrase searching inside double-quotes.
"Forbidden terms" is a different way of saying NOT or using the minus sign .
The phonetic search sounds great, but I am often frustrated by it because so many
websites misspell so many words, Exalead is going to find those misspelled words
first (try: [geneology] to see what I mean). However, the phonetic search
successfully figured out that [criptografy] meant [cryptography]. The phonetic search
has genuine utility.

The approximate spelling option can be similarly frustrating. A search on
[programme] will find a few sites containing program, programmen, or programs, but
usually the results are for the actual term searched, in this case [programme].
However, it worked very well with [colour], finding a good mix of color and colour and
the approximate search on [geneology] found genealogy.
What I like much, much better is Exalead's regular expression patterns option,
which amounts to a true wildcard search. Here's how it works:
Use a forward slash (I) at the beginning and end of the term; use a period (.) to
indicate one missing term; if you are not sure how many letters are missing, use
the wildcard (*) after the period. For example, the query [lcrypt.*cl] will find
cryptographic and cryptologic:
