# search for something - open search dialog / LIB|TEST # this works ! - thank the wizards LIB&TEST # this doesnt. ACPI&LIB # this would match 1st find by 1st line (a positive test) its not a well-formed search pattern/regex in any system I know, but it has an implied meaning ( grep FOO .config | grep TEST ) and utility - to see if FOO has a *TEST*, and where is it ? Anyone want to look under the hood, see how its done ? some UI tests: searching '&' acts like a literal, returns no matches found searching '|' doesnt search, leaves u on enter-search-term dialog nor does '|FOO' So '|' is recognized as special Also, the search dialog will time out, (below is eventual response, I think on '|FOO' but response to '|' is "the same" ───────────────────────────────────────────────────────────────────────────────────── ┌───────────────────────────────────────────────────── Search Results ──────────────────────────────────────────────────────┐ │ Symbol: -17 [=-17] │ │ Type : unknown │ │ │ │ │ │ Symbol: 0 [=0] │ │ Type : unknown │ ... goes on for a while.... If you can find that spot in code, and make '&' special, I think youre more than half way there.
