The following query returns results from various languages on S2

r:^github\.com/sourcegraph/sourcegraph$ lang:yaml if ... else ... patternType:structural

However, locally and on .com the language filter works

• S2: https://sourcegraph.sourcegraph.com/search?q=context:global+r:%5Egithub%5C.com/sourcegraph/sourcegraph%24+lang:yaml+if+...+else+...&patternType=structural&sm=0
• .com: https://sourcegraph.com/search?q=context:global+r:%5Egithub%5C.com/sourcegraph/sourcegraph%24+lang:yaml+if+...+else+...&patternType=structural&sm=0
