Entity Queries
The root of an entity query targets an entity index. Therefore, all _stp_ properties should be indexed, as should any properties you may want to query. Use case-insensitive indexing to yield greater search results.
Entity Patterns
The basic pattern for an entity query follows the rules below.
<EntityType> <Property> <value>
<EntityType> <Property> <Operator> <value>
<EntityType> <Property> <value> <condition> <Property> <value>
<EntityType> <Property> <Operator> <value> <condition> <Property> <Operator> <value>
<EntityType> <value>
<Property> <value>
<Property> <Operator> <value>
<EntityType>
<value>
Query Operators
The following operators are valid for entity queries. Additionally, you can use wildcard characters. An asterisk (*) represents any character sequence, and a question mark (?) represents any single character.
