How do I combine "is recurring" with other filters?

[daddydave]

The task query syntax does not like
(is recurring AND due 2023-10-06 2023-10-19) OR (is not recurring AND done 2023-10-06 2023-10-19)

The whole block for a shorter version of this is

```tasks
is recurring AND due 2023-10-06 2023-10-19
tags include bill
hide edit button
hide backlink
hide tags
```

The error I get is

"Tasks query: do not understand query
Problem line: "is recurring AND due 2023-10-06 2023-10-19"

Hi @daddydave,

The Syntax section of the Combining Filters page explains what is going on:

---

Syntax

One or more filters can be combined together in a line, via boolean operators, to create a new, powerful, flexible filter.

The following rules apply:

• Each individual filter must be surrounded by parentheses: ( and ).
• Operators supported are: AND, OR, NOT, AND NOT, OR NOT and XOR.
• The operators are case-sensitive: they must be capitalised.
• The operators must be surrounded by spaces.
• Use more ( and ) to nest further filters together.
• There is no practical limit to the number of filters combined on each line, nor the level of nesting of parentheses.

---

So the problem is that not all of your filters are surrounded by parentheses: ( and ).

So you should change this:

(is recurring AND due 2023-10-06 2023-10-19) OR (is not recurring AND done 2023-10-06 2023-10-19)

to this:

( (is recurring ) AND ( due 2023-10-06 2023-10-19) ) OR ( ( is not recurring ) AND ( done 2023-10-06 2023-10-19) )

Once the query is interpreted OK, you can then add the explain instruction to confirm that the logic is what you intended...

@claremacrae Awesome, thank you for the fast and extremely detailed response!

For posterity, here is what I ended up with for now. I use a Templater template to generate this every couple of weeks when I get paid. The tasks (bills) remain visible until the end of the pay period, completed (paid) or not. Adding in non-recurring bills made it slightly little more complicated.

```tasks
((is recurring) AND (due 2023-10-06 2023-10-19)) OR ((is not recurring) AND ((not done) OR (done 2023-10-06 2023-10-19)))
tags include bill
hide edit button
hide tags
sort by start
```

Super - thanks for recording it... 🙏
