Search on multiple Labels

[Rudy Desmet]

What is the difference between [in the general Search bar]:

labelText:Label1 AND labelText:Label2

and

labelText:"Label1 AND Label2"

The answers I get in my spaces are slightly different

The standard syntax to use in order to do selections on multiple labels in the Search-bar is :
labelText:Label1 AND labelText:Label2
In my search to find an easier way to combine selections on multiple labels, I noticed that
labelText:"Label1 AND Label2"
also works.

As the volume of documents is high, and the number of labels to combine is often 4-5, I can not ask my users to continuously use the first type of rule.

The second would do.

But I noticed a slight difference.

By testing these search options I have following questions:

1. Concerning the search on an individual Label:
   What is the difference in using “labelText:Label1” in the standard search field and searching for  “Label1” in the Search Filter “Label”?
   Searching on “home” with the first syntax gave me 38 results, with the second I’ve got 31 results. With the first, it also gives results containing “home” in a part of the document label (in this case documents containing the label “content-home-page”.
   Searching on “claims” (with an ‘s’ at the end) with the first syntax gave me 35 results, with the second I’ve got 34 results. With the first, it also gives a result containing “claim” as a label (without the ‘s’ at the end).
   Any reason why?

Concerning a search on multiple Labels:
Is “labelText:"Label1 AND Label2" a correct alternative for “labelText:Label1 AND labelText:Label2” ? Or is there a difference also?
