Prefix search is a search for a line of text that begins with a given character or group of characters (prefix). Prefix search is a special case of wildcard search.
To use this Prefix search app, you need to enter the beginning characters of a word in the query text box and end it with the wildcard character "*", meaning an arbitrary text string or the empty string.
A prefix search example is the query "he*", for which the application will find in documents, for example, the following words:
In this application, the wildcard character "*" denotes the ending of only one separate word. If you need to find a phrase consisting of several words, all words from a query in a file, or any word from a query in a file, then you must select the appropriate option under the query text box. In this case, each word of the query can contain wildcards, and the words are separated from each other by spaces.
The GroupDocs.Search full-text search engine on which this prefix search application is based also supports:
You can perform prefix search in many file formats. Please see the full list below.
