-Three basic types of indexes allow SQL statement to be optimized and provide features including textual search, fuzzy searches and geographical searches. ​ Installation can be as simple as placing indexes on the columns involved in a query. ​ A collection of advanced options allow access to specialized features that are useful for individual situations. 
  
-Omnidex indexes are easily created using either the Omnidex Administrator or Omnidex SQL statements. ​ Indexes can be built in batch, greatly reducing the time required to build the indexes.  ​+===== Overview =====

-  - [[#​What_does_an_Omnidex_index_do|What does an Omnidex index do?]] +Three basic types of indexes allow SQL statements to be optimized. ​ They also provide features such as textual searches, fuzzy searches and geographical searches. ​ Basic Omnidex indexes ​provide the bulk of Omnidex ​functionality,​ optimizing criteria, table joins, aggregations and ordering. ​ QuickText ​indexes ​provide basic textual searches on columns like name and address fields, product descriptions and general text.  FullText ​indexes ​provide sophisticated text indexing designed for large blocks of textual data.  ​

 +Omnidex also has advanced options that help optimize the complex or unusual situations. ​ One example of this is Index Groups, which index multiple columns as though they were one column. ​ Another example are geographic indexes which index latitude and longitude coordinates in preparation for geographic searches.
 +
 +Omnidex Indexes are installed by simply designating indexes on the columns involved in a query. ​ There are times when indexing options are valuable, and there are also times when multi-column indexes are created. ​ Once the indexes are designated, all indexes can be built concurrently,​ greatly reducing the time required to build the indexes.  ​
