Search function doesnt work properly

**Describe the bug**
The search function on my markets on the exchange page doesn't work properly. From a users perspective this is a pretty basic feature that everyone expects to work 100%. If a user comes to bitshares to trade a specific market, searches and it returns no results then we just lost a user. I don't know how much work is involved in fixing this but it needs doing. How can we market ourselves as a decent DEX if we cant even provide a working search function for them to find markets?

**To Reproduce**
Go to exchange page, go to find markets, type in bridge.eth in quote currency and open.eth in asset name.

**Expected behavior**
Should return the open.eth-bridge.eth market

**Desktop (please complete the following information):**
- OS: ubuntu 16.04
- Version 190227


The issue names no files or tests; start by reproducing the exchange page's Find Markets flow with bridge.eth as the quote currency and open.eth as the asset name. Trace the frontend search entry point and verify that the open.eth-bridge.eth market is returned, matching the expected behavior.
