Time passed and here is the result: 1search_jq with query, maybe a preview in stable condition.
- fast, small footprint
- without load in <body> tag, so it is no problem to mix with other snippets

Because some sidebar hooks are missing, please have a look at the README.txt or the previous patch .
I listen for response ...
