For example, "TAP - I;" will sometimes show up in searches for "TAP - II;" because all the characters from "TAP - I;" are included in "TAP - II;"
Actually, this should not happen if you include the semi-colon as the criteria.
Hi, I know this has been over a year, but I wanted to say I discovered the reason for this.
I started to include the semi-colons for the same thing that Phil had thought: I thought it would make the value unique.
However, at least this version of FileMaker Pro conducts somewhat of a loose search when using CHECK BOXES.
If you search for TAP I;, fields with values that CONTAIN the word "tap" and the letter "i" will come up.
So, TAP II;, TAP III;, and so forth will come up.
I noticed this because I was searching for a field value MODERN 3-6, and a record that included the values MODERN 6-9 and BALLET 3-6 came up because the value included both the term "modern" and the numbers "3-6" even though they were not in consecutive order as I had searched for.
