Wildcard character limitations

A search that contains a wildcard character (*) is limited to expanding to a maximum of 1024 matching search terms.

This limitation is due to the way that the text search server processes queries. The internal query processing takes a term such as "termstart*" and expands the term similar to looking up a word in a dictionary. For example, matching results are "termstart1 or termstart2 or . . . termstart1024" until the limit of 1024 terms is reached.

Due to this limitation, the internal query processing of a wildcard character search might return an error if the search reaches the maximum of 1024 matching search terms.
