ELLQL (for EXALEAD Low Level Query Language) exposes all advanced features of the
EXALEAD search and index stacks.
Internally, all UQL (for User Query Language) queries entered by users are transformed into
ELLQL. ELLQL is mostly used by custom programs to enrich user queries. In the Administration
Console, you can write ELLQL in the Search Logics > Search Logic Name > Query
Template tab. You can also directly enter ELLQL in search fields, using the eq
parameter instead of the q parameter (used for UQL queries).
