The "+" symbol means a clause of a boolean query that "must" be present, as
opposed to "should" (optionally) be present. This is equivalent to the "AND"
operator.
The "|" means "OR" for a disjunction maximum query to indicates the
alternatives - at least one of the alternatives must match.

When I go through the debug results I found this. Can you explain me what
is the + and | sign means.
+(
+DisjunctionMaxQuery(
(
Exact_Field1:"samplestring1"^0.6 |
Exact_Field2:samplestring1^0.5 |
Field1:samplestring1^0.9 |
Field2:samplestring1
)
)
+DisjunctionMaxQuery(
(
Exact_Field1:samplestring2^0.6 |
Exact_Field2:samplestring2^0.5 |
Field1:samplestring2^0.9 |
Field2:samplestring2
)
)
)

If you are looking for that level of understanding, you are best
enabling the debug flag. Then you will get a full breakdown of what
matched which field and why. Including scores, preferences, etc.
Possibly with debug.explained.structured enabled:

Most people do not want to deep dive into debug info. But I am getting
the feeling this would be right where you want to go.
