You can modify this, theres settings for - how much context - chunk size

We had to do this, 3 best matches but about 1000 characters each was far more effective than the default I ran into of 15-20 snippets of 4 sentences each

We also found a setting for "when do you cut off and/or start" the chunk, and set it to double new lines

Then just structured our agentic memory into meaningful chunks with 2 new lines between each, and it gelled perfectly.

( hope this helps )
