Why Some of the Stocks are not visible / searchable in Fyers Web Portal, however we can find the same stock in other portals like tradingview?

I  have noticed the same issue many times that, 

Ex: 

when i search for "BLSINFOTE"  Stock in Tradingview Website. i can view the chart and Explore. but when i search for the same Stock in Fyers Web Tradingview portal, i see No Symbols Matched Your Criteria.

Please help on this.
