How to Convert company name to symbol or sid in Research

Hi,

Recently, I try to test some company's performance in the history.

I find that some companies use the same ticker when another company delisted before.

When I try to test that, I can just know the performance of new one in research environment.

For instance, In my notebook, I want to know the historical performance of HCC Insurance Holdings(ticker: HCC)

But I what I get is Warrior Met Coal Inc.(ticker: HCC) and their performance is nan because they had not listed yet.

I find many post in Quantopian discuss about converting SID to Symbols or Symbols to SID.

But how can I convert given name of company to symbols? (How can I get historical performance of HCC Insurance Holdings?)

Thanks!
