Nonunique indexes permit duplicates values in the indexed column or columns. For example, thefirst_namecolumn of theemployeestable may contain multipleMikevalues. For a nonunique index, the rowid is included in the key in sorted order, so nonunique indexes are sorted by the index key and rowi...

Duplicate values must be removed before a unique index can be created on the column or columns. Columns that are used in a unique index should be set to NOT NULL, because multiple null values are considered duplicates when a unique index is created....
A disk-based rowstore nonclustered index contains the index key values and row locators that point to the storage location of the table data. You can create multiple nonclustered indexes on a table or indexed view. Generally, nonclustered indexes should be designed to improve the perform...

Beware that this is a linear search, unlike lookups by key, and that multiple keys can map to the same value and this will find only one of them. Note also that unlike most collections' indexOf methods, this method compares values using == rather than equals. Java documentation for androi...
