Return multiple results per file

[spasche]

This is a clone of #154 since it still affects latest version 2.5.2

Steps to reproduce:

> qmd --version
qmd 2.5.2

> mkdir /tmp/gh-154
> cd /tmp/gh-154
> curl -o llms-full.md https://docs.openclaw.ai/llms-full.txt

# there are plenty of "channel" words in the document:
> grep -i channel llms-full.md|wc -l
5146

# but only one result is returned:
> qmd --index=gh-154 collection add .
> qmd --index=gh-154 update
> qmd --index=gh-154 search channel --all --json | jq .[].file -r
qmd://gh-154/llms-full.md?index=gh-154

Reproduces trivially locally, making qmd quite useless for my relatively trivial use case. ripgrep provides more useful responses. Doesn't require large files, just multiple mentions even in short files. Ranking isn't doing anything to boost the far more specific matches elsewhere in the file.

I tried qmd today for the first time on my Markdown notes. Like you, I was surprised that qmd seems to work on the assumption that notes shall be split into many small files. I would love to see support for finding multiple hits within larger notes!
