Advanced filter logic

Overview

The contacts list supports nested boolean filter expressions. You can combine multiple filters with AND, OR, NOT, and parentheses to model complex supporter queries — for example, "major donors in California who haven't given in the last 12 months."

How it works

As you add filters, GiveLink shows progressively more controls:

1. One filter — just the filter chip.
2. Two filters — a Match ALL / Match ANY toggle appears between them.
3. Three or more filters — a Filter logic text field auto-expands below the chips. Each chip gets a number (1, 2, 3, …). Write an expression that references those numbers.

Grammar

The filter logic field accepts:

• Chip references — positive integers that match the number badges on your chips.
• AND, OR, NOT — case-insensitive, separated by spaces.
• Parentheses — to group subexpressions.

Examples

Operator precedence

AND binds tighter than OR. 1 OR 2 AND 3 means 1 OR (2 AND 3). Use parentheses when you want a different grouping.

Sharing a filter

The full expression is encoded in the URL. Copy and paste the URL to share a filter with a teammate.

Known limitations

• Text filters use ASCII case-folding. Non-ASCII characters (é, ñ, …) don't match their uppercase/lowercase variants — use Contains and expect exact matching on case-variant characters.
• Saved filters (naming a filter and recalling it by name) are coming in a future release.
• Drag-reordering chips isn't supported yet. Chips are numbered in the order you added them; removing a chip renumbers the rest.
