Patterweb/UTEL provides a wide range of options for constructing text searches, allowing for sophisticated text-database queries. See Search Functions.
The number of results displayed, the amount of surrounding context and the format of the output text can be modified by the user; see Output Display Options.
A single-word search identifies only exact occurrences of the specified word; in the above example, instances of the words "horses", "horseman", etc., will not be displayed in the results. To search for words beginning with the character sequence "horse", specify the search pattern as "horse*".
Important: Case is not significant. horse, HORSE, and HorSE are equivalent search strings. Do NOT include quotes (single (') or double (")) in the search string. Hyphen (-) is treated as a letter. The input area accommodates 240 characters. This is more than enough for single-word searches, but is useful for more complex search patterns (see below). With graphical browsers, the input window scrolls to the left if more characters are entered than can be displayed at one time.
To search for alternate word-forms, enter words separated by commas in the query input field:
An alternate character sequence can be "empty", as in the following search for dine, dined or diner:
Alternate character sequences can also be "nested", as in the following search for undertake, overtake, vndertake or ouertake:
One application of this feature is querying for "remote proximity" of two search patterns, identifying occurrences of one pattern near (but not very near) a second pattern. For example, to search for occurrences of "queen" within eighty characters but no nearer than twenty-five characters, specify the following query:
Another is to build complex proximity searches:
Important: Three-level searches are evaluated cumulatively. That is, the first two patterns are combined with the first operator, and the result is applied to the third pattern using the second operator. ((roman followed-by cathol*) not-near pope) is not the same as (roman followed-by (cathol* not-near pope)).
Patterweb allows the user to restrict searches to texts matching specific criteria.
