Search should allow simple arithmetic expressions

[lordpixel23]

e.g. I want to see all transactions > $100, I should be able to type something like '> 100' in the search field.

Implementation probably has some issues:

• the simplest thing you could do is look at the first character of the input and if it is > or < or = enter a special mode where you interpret the search string differently
• naturally that leads to issues with the way developers would expect to be able to type >= or == but probably should ignore those as people who don't code don't think in those terms
• similarly, full blown expressions (as in SPEL or JUEL) like > 100 && < 150 will likely just confuse people
• question arises of what to do with foreign transactions, how to search in GBP vs. USD

Probably the best thing is to keep it really simple and allow > 100, < 100 and = 100 and not much more than that.

If I were really going to push the boat out, then something like '≥ £100' could be allowed too, but, the reality is typing stuff like that on Windows is really hard (how ridiculous is that in 2022?) and only a subset of Mac users know how to do it :-)
