Omnidex provides several powerful text searching capabilities that allow developers to provide users with very fast and flexible text search applications. The Omnidex text search features include keyword, synonym, proximity, phonetic, misspelling and spell-checked searches, as well as useful thesaurus and form search capabilities and a dictionary for definition retrievals. Proximity searches also enable rank and relevancy score retrieval, as well as context retrieval with optional an highlighting feature.
All of these text search capabilities are available on all textual data type fields, including extremely large amounts of data contained in CLOB data type fields as well as text documents external to the database. The text search capabilities are available for use in any Omnidex application, some by default and some through specific Omnidex extended functions.
At this time, Omnidex supports plain text and html text documents external to the database.
All columns in a table, except for the last column, must have an offset of 65,535 bytes or less. This means that there may be only one data type with a length greater than 65,535 AND it must be the last column in the table definition. Therefore, there can be only one column per table, the last column, of any of the following data types: CSTRING with a length of 32,768 bytes or more, CLOB, OMNIDEX CLOB, BLOB, or OMNIDEX BLOB.
The size limit depends on the data type See Supported Data types for details.
