## TL;DR

A community member proposed the fix and a maintainer invited a PR. This inconsistency was fixed in Marqo v2, where the \_highlights return type was made consistent across search methods.

## Steps

1. This inconsistency was fixed in Marqo v2, where the `_highlights` return type was made consistent across search methods. If you are on Marqo v1, the workaround is to handle both types client-side; upgrading to v2 resolves it.

## When to use

You are seeing this: The \_highlights field in Marqo search results had different types depending on the search method. Use this skill when you run into "Marqo _highlights return type differs between LEXICAL and TENSOR search".

## 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.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
