Developing a software knowledge base using WP and this wonderful plugin, whe have noticed that it we enter a search query like:
[Software name] + [two-digit version number]
Then we only get two results when there are hundreds of pages containing that expressions.
But if we put the query in quotes:
"[Software name] + [two-digit version number]"
Then Relevanssi lists all the relevant results...
What might be the reason for this? (Minimum word length to index is set to 1 and none of the words are included in the stopwords' list.)
