No support for SQL Full Text Index in Direct Query Mode

The visual does not support FULL TEXT index type. My guess is that this is depending on the DAX-SQL translation and nothing that you can do anything about. I Create this issue anyway just to inform that the feature is missing
Using CONTAINS() instead of CHARINDEX() would have made the visual supporting FULL TEXT index types

In short, the DAX code below:
FILTER(
KEEPFILTERS(VALUES('Table'[Column])),
SEARCH("/Text to be searched for/", 'Table'[Column], 1, 0) >= 1
)

Is translated into the SQL code below:
WHERE
(
CHARINDEX(N'/Text to be search for/',
COALESCE([t10].[Column], '')
)

And CHARINDEX does not take advantage of indexes of type "FULL TEXT"

/* DAX and SQL (short versions) code below */

The DAX Code generate looks something like below:
// DAX Query
DEFINE
VAR __DS0FilterTable =
FILTER(
KEEPFILTERS(VALUES('Table'[Column])),
SEARCH("/Text to be searched for/", 'Table'[Column], 1, 0) >= 1
)

VAR __DS0Core =
CALCULATETABLE(
SUMMARIZE(
'Table',
'Table'[Column],
'Table'[Column2],
'Table'[Column3]
),
KEEPFILTERS(__DS0FilterTable)
)

VAR __DS0PrimaryWindowed =
TOPN(
501,
__DS0Core
)

EVALUATE
__DS0PrimaryWindowed

The SQL looks something like below:
// SQL
SELECT
TOP (501) [t10].[Column], [t10].[Column2], [t10].[Column3]
FROM
(
(select [$Table].[Column] as [Column],
[$Table].[Column2] as [Column2],
[$Table].[Column3] as [Column3]
from [schema].[Table] as [$Table])
)
AS [t10]
WHERE (CHARINDEX(N'/Text to be search for/', COALESCE([t10].[Column], '')) >= 1)

No files, tests, or entry points are named. Start by tracing the direct-query behavior described in the issue and determine whether this visual controls the DAX-to-SQL translation from SEARCH to CHARINDEX; done means confirming whether FULL TEXT index support is possible here or documenting that it depends on an external translator.
