Según https://developers.google.com/fusiontables/docs/developers_reference OR operations are not allowed as part of filter conditions. So I'm trying to come up with a creative way to solve the following:
I have a fusion table backed google map with hundreds of places and want to filter it to only places that have 'tags' or a 'title' containing a search parameter.
Ideally I could just use the following as my filter condition:
tags CONTAINS IGNORING CASE 'searchterm' OR title CONTAINS IGNORING CASE 'searchterm'
But the fusion table API simply doesn't allow it. So what to do? Make 2 separate queries, then filter out the duplicates? That means I can't use the nice FusionTablesLayer pre-rendered tile functionality.
¿Qué haría usted?

A possible answer is to pre-render the data within the table. Essentially add another column which is an aggregate of tags and title. Then I only need to query the one 'tags_or_titles' column. Of course this means more data munging beforehand when I export the data into the fusion table and doesn't feel so nice and clean...
How about adding a column to your table called "Show_In_Results",
then running two separate queries to update that column for each row of data based on whether the search term is found in the specific column or not.
UPDATE 'table_id' SET Show_In_Results = 1 UPDATE 'table_id' SET Show_In_Results = 1 WHERE tags CONTAINS IGNORING CASE 'searchterm' UPDATE 'table_id' SET Show_In_Results = 1 WHERE title CONTAINS IGNORING CASE 'searchterm' and Show_In_Results <> 1
Then when you render your map layer:
SELECT 'columns' FROM 'table_id' WHERE Show_In_Results = 1
