Airtable filterByFormula substring matching with SEARCH() instead of equality

TL;DR

Use SEARCH([term], [Column]) > 0, and wrap both sides in LOWER() for case-insensitive matching. If you need substring filtering on an Airtable column, dont use equality in filterByFormula.

Steps

1. If you need substring filtering on an Airtable column, dont use equality in filterByFormula. Use SEARCH([term], [Column]) > 0, and wrap both sides in LOWER() for case-insensitive matching. Note that select() pages at 100 records, so loop through pages to collect everything.

When to use

You are seeing this: The accepted answer points to the SEARCH() formula as the substring matcher: SEARCH([your term], Column) > 0 returns every row where the term appears anywhere in the column value. Use this skill when you run into "Airtable filterByFormula substring matching with SEARCH() instead of equality".

When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

Edge cases

• Note that select() pages at 100 records, so loop through pages to collect everything.

Source: Stack Overflow #42429056 (accepted answer, 11 votes): the asker used Column equals [term] in filterByFormula and only got exact matches. The accepted answer points to the SEARCH() formula as the substring matcher: SEARCH([your term], Column) > 0 returns every row where the term appears anywhere in the column value. It also warns the docs promise nothing about case-insensitivity, so wrap both the column and the term in LOWER() when you want a case-insensitive match, and keep the term at least 2 characters for performance.

Verified resolution: If you need substring filtering on an Airtable column, dont use equality in filterByFormula. Use SEARCH([term], [Column]) > 0, and wrap both sides in LOWER() for case-insensitive matching. Note that select() pages at 100 records, so loop through pages to collect everything.
