When you execute some queries on your SQL Server, are you sure the catalog is being imported?
With this simple script you can know which is the Index status.
DECLARE @CatalogName VARCHAR(MAX)
SET @CatalogName = 'TEST_FullIndex'
SELECT FULLTEXTCATALOGPROPERTY(@CatalogName,'ItemCount') as NumberOfItems,
FULLTEXTCATALOGPROPERTY(@CatalogName,'ImportStatus') as ImportStatus,
DATEADD(ss, FULLTEXTCATALOGPROPERTY(@CatalogName,
'PopulateCompletionAge'), '1/1/1990') AS LastPopulated,
(SELECT CASE FULLTEXTCATALOGPROPERTY(@CatalogName,'PopulateStatus')
WHEN 0 THEN 'Idle'
WHEN 1 THEN 'Full Population In Progress'
WHEN 2 THEN 'Paused'
WHEN 3 THEN 'Throttled'
WHEN 4 THEN 'Recovering'
WHEN 5 THEN 'Shutdown'
WHEN 6 THEN 'Incremental Population In Progress'
WHEN 7 THEN 'Building Index'
WHEN 8 THEN 'Disk Full. Paused'
WHEN 9 THEN 'Change Tracking' END) AS Status
FROM sys.fulltext_catalogs AS cat
