Is there an option in Powerapps to split a search text into individual strings and to display on a gallery only items that include "all" strings? - full-text-search

Question

my case is similar to this case: Click here!
I have a gallery which displays items from a Collection. I already added a Textinput.Text to give customers the opportunity to search for items.
But, what I am struggling with is to implement a "full-text" search.
The solution #carlosfigueira offered in the above-mentioned question works perfectly to split the search text but I would like to have display items on the gallery only that includes all individual strings.
This is my code for items on the gallery
Filter(
CustomListIssues;
Sum(
ForAll(
Filter(
Split(
InpSearchString.Text;
" "
);
Len(Trim(Result)) > 0
);
If(
Result in 'Title EN';
1;
0
) && "Unresolved" = Status && If(
!IsEmpty(lbSearchDepartment.SelectedItems.Result);
lbSearchDepartment.Selected.Value = Departement;
"" in Departement
)
);
Value
) > 0
)
CustomListIssues: A collection where I store all list items
InpSearchString.Text: Search TextInput.Text
'Title EN': The column I would like to search in based on the given search string

Given search string
Trim(InpSearchString.Text)
The gallery which displays items from a Collection
Expected result:
I would like to have display items on the gallery only that includes all individual strings
Thanks in advance

If you want to have all strings instead of one of them, you can slightly change the logic of the expression. Before it would sum 1 if a word is in the title, and check that the result is more than 0 (so if any is present, then the item would be returned). In this modified expression below, we're adding 1 if each word is not in the title, and at the end we compare the sum with 0 - if it's not zero, then at least one word was not found, and we don't return the record.
Filter(
CustomListIssues;
Sum(
ForAll(
Filter(
Split(
InpSearchString.Text;
" "
);
Len(Trim(Result)) > 0
);
If(
Result in 'Title EN';
0;
1
) && "Unresolved" = Status && If(
!IsEmpty(lbSearchDepartment.SelectedItems.Result);
lbSearchDepartment.Selected.Value = Departement;
"" in Departement
)
);
Value
) = 0
)
