Indexing works similarly with almost any field type, text, numbers, date, and even spatial
data types such as the Esri shape geometry type. Indexes created on shape columns are
called spatial indexes, which have the same concept as attribute indexes. Both of them
shrink the query search domain to achieve greater performance.
Note
A spatial index is an index that is used on spatial data type columns such as geometry. It
allows the spatial query to be run on a subset grid instead of an entire geodatabase grid.
