No support for SQL Full Text Index in Direct Query Mode

[erapade]

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)

Just pinging this issue to keep it alive. Yes SQL full text index is probably not supported in the open API. But if Microsoft are serious in their investments in Direct Query I think it would be a great idea to support this. So this is probably not a request to this visual, it’s rather a request bro the API or direct query connector.
