If a topic title has the string `CHEM894` and somebody searches for `894`, that topic will appear as you would expect. But if it were `CHEM123` and somebody searches for `123`, it doesn’t get found. It’s weird. Furthermore, if somebody searches for `chem 1`, the topic _will_ appear. `CHEM321` doesn’t work either with similar behaviour. It looks like the built-in search engine won’t search for certain numbers within words. There are other unexpected inconsistencies with the same theme, like “chem 123” _sometimes_ finds a title with “chem123” and sometimes doesn’t. Could somebody maybe try to reproduce this behaviour?

edit: adding ‘chem132’ to test this site’s search engine.
