SUMMARY:
    If you quote the phrase to search for an exact phrase rather than all the words
    (using the Baloo index). Dolphin allows you to type "Just this" and gives you
    the hits with the exact match however when you press return Dolphin strips the
    quotes and returns the hits with all words.

STEPS TO REPRODUCE:
1...
    Make sure Baloo is running and indexing your test folder

2...
    Create a couple of test files:
        $ echo "Just this" > letter-to-mary.txt
        $ echo "Just want to say this" > letter-to-agatha.txt

3...
    Open Dolphin search, choose "Content" rather than "Filename" and
    type, with double quotes, "Just this" and check the results. Then press return.

OBSERVED RESULT:
    The search for "Just this", as you are typing, gives you just the letter-to-mary.txt
    (as it is an exact match)

    When you press return, you get both the letter-to-mary.txt and letter-to-agatha.txt

    You will see the search string "as used" displayed the Dolphin title change
    from '"Just this"' to 'Just this', the results switch from matching the phrase to
    matching all the words

EXPECTED RESULT:
    If the search string is quoted, it stays quoted.

SOFTWARE/OS VERSIONS:
    Neon Unstable
    Dolphin: 24.11.70
    Plasma: 6.1.90
    Frameworks: 6.7.0
    Qt: 6.7.2

ADDITIONAL INFORMATION:
    This affects Baloo searches as Dolphin's internal search does not find quoted phrases
    (See Bug 494584)

    Note that single quotes round the phrase are kept, it is only the double quotes that
    are lost, and also it only fails with "Content" search, not if you have selected
    "Filename".
