Application Express :: How Does Filter Operator Contains Work On Interactive Reports

Jul 30, 2012

I'm creating Tool Tip definitions for the Operators in the Filter on the Interactive Reports. I was looking for a definition for the 'Contains' operator and from what I've found this operator is used to do a text search and it returns a relevance score for every row selected.

I've also read that in order for that score to be determined that the column(s) need to be indexed with a CONTEXT index. Non of the columns in the tables are indexed with a CONTEXT index, however, when I put a value in the Expression box for a column I get a record returned.

If I run the same query in PL/SQL Developer like:
SELECT <column>
FROM <table>
WHERE contains(<column>,<search text>,1) > 0;

I get an error that the column is not indexed, so how does it work in APEX?
