From the original post we have:
Code:
find path \( \
   \( [folder-condition A] \) -prune -o \
   \( [folder-condition B] \) -prune -o \
   \( [folder-condition C] \) -prune \
\) -o \( \
   \( [file-condition D] \) -o
   \( [file-condition E] \) \
\) -o -print

You have no folder pruning conditions and two file pruning conditions so, the find should have been:
Code:
find "$SEARCH_PATH"  \(
    -false
\) -o \( \
    \( ! -newer "$FILE_DATE_REF_DEB" \) -o
    \(  -newer "$FILE_DATE_REF_END" \)
\) -o -print

Which can be simplified to:
Code:
find "$SEARCH_PATH" \( ! -newer "$FILE_DATE_REF_DEB" -o -newer "$FILE_DATE_REF_END" \) -o -print

and further simplified to
Code:
find "$SEARCH_PATH" -newer "$FILE_DATE_REF_DEB" ! -newer "$FILE_DATE_REF_END" -print

This find is equivalent to the find from the original post which returned 32 elements.

Hope this helps you work out was is going on. Note that -prune only comes into the find when you have conditions that remove directories (and all files below them).
