    For example, one might wish to find all occurrences of a "word" despite it having alternate spellings, prefixes or suffixes, etc. Another more complex type of search is regular expression searching, where the user constructs a pattern of characters or other symbols, and any match to the pattern should fulfill the search. For example, to catch ...

    Search for strings of text and optionally replace them, progressing one at a time or replacing all occurrences at once. If the regular expressions check box is selected, then the targeted search term is interpreted as a symbolic "expression", called a "regular expression", which will act as a pattern to select targets for replacement. Any ...

    In computer science, the Knuth–Morris–Pratt algorithm (or KMP algorithm) is a string-searching algorithm that searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters.
