Searching a channel Problematic

What i noticed:

  1. Search Command Ctrl- F to search for this: “0188-02-23” returns no results.
    However, Search Command Ctrl- F to search for this: “0188” returns all possible results INCLUDING
    “0188-02-23”.
    What could be the issue?

Hey,

what search backend are you using? Database search? Bleve? Do the results change when you put the text in quotes?
What server version is this?
