I'm using Oracle Database and table consist of Title,Description,Language columns. Using BCS and creating BDCM file, I'm able to get all the data from Oracle Database. I could make managed properties (owsCusTitle,owsCusDESCR,owsLanguage) and link this to the crawled property and everything is OK. Now in my application, I'm showing data using search rest API like this:
But there are many records with owsCusTitle column as blank. I don't want to show those records. Is there any way to filter custom managed property in the query itself ?
