Query options selected by menus or buttons

These checkboxes allow some control of the query specification.


Case insensitive:
By selecting this checkbox the query will become case insensitive (lower case and upper case letters differ). Otherwise, the query will be case sensitive. The default is case insensitive.


Keywords match on word boundaries:
By selecting this checkbox, keywords will match on word boundaries. Otherwise, a keyword will match part of a word (or phrase). For example, "network" will matching ``networking'', "sensitive" will match ``insensitive'', and "Arizona desert" will match ``Arizona desertness''. The default is to match keywords on word boundaries.


Number of errors allowed:
Glimpse allows the search to contain a number of errors. An error is either a deletion, insertion, or substitution of a single character. The Best Match option will find the match(es) with the least number of errors. The default is 0 (zero) errors.

Note: The previous three options do not apply to attribute names. Attribute names are always case insensitive and allow no errors.
