Hi @Nils_Langner,
Thanks for your patience. I believe the scoring you’re seeing (in specific reference to the 2 documents in your screenshot) is due to the other fields containing the "file" term. I did a quick find on the document with the highest score and found there are 31 instances of the word "file" which would impact the score since you have indexed all fields.
For example, in my test environment, I have the same 2 documents where the higher scoring document does not contain contain "phar file decompress" in the description:
db.text.find({$text:{$search:'phar file decompress'}},{score:{'$meta':'textScore'}})

There are multiple instances of the term "file" inside the plainQuestions and questions field for the first document. After removing this and performing the same .find() with the $text operator, we can now see the score is lower than the file that contains the terms "phar file decompress" in the description field:

Note: The above test collection contained the following indexes:
[
{ v: 2, key: { _id: 1 }, name: '_id_' },
{
v: 2,
key: { _fts: 'text', _ftsx: 1 },
name: 'textIndex',
weights: { '$**': 1, description: 2, name: 3 },

language_override: 'language',
textIndexVersion: 3
}
]
Although I understand removing those fields is not what you’re after, I hope it helps in understanding the scoring behaviour you had seen. In comparison to this, with the unaltered versions of the same 2 documents, I created a similar index with following weights:
test> db.text.createIndex({'$**':'text'},{weights:{description:6,name:8}})
$**_text
Which then resulted in the document containing all the terms of the text search in description to score higher:
test> db.text.find({$text:{$search:'phar file decompress'}},{score:{'$meta':'textScore'}})

In saying all the above, hopefully the Assign Weights to Text Search Results documentation may be of use to you.
