I built a collection with the syntax: type:lexicon OR encyclopedia OR lexicon OR dictionary. Why are the exegetical summaries series showing up?
Is type:(lexicon, encyclopedia, dictionary) better?
Yes, I think so. I tried to do that at first without the parenthesis… which obviously didn't work. I notice now that I had "lexicon" listed twice… It seems there was a fourth type I wanted to add and must have misread the list.
It does seem interesting that I get different results with the following:
VS
I would have thought that all three would have produced the same results. Certainly there was some user error… is there a bug as well?

Just to clarify… I'm not talking about THESE bugs. [:D]
type:lexicon OR encyclopedia OR dictionary OR lexicon [I get 145 results with the mistaken addition of a second "lexicon"]
The second "lexicon" searches for the word appearing in many library columns, including resource description:
The "lexicon" library search includes a number of other resource types.
Keep Smiling [:)]

I think KS4J might be correct. I suspect that the type only applies to the first term. The program then searches for the other terms rather than searching those types.

Library filters (e.g., type:) bind more tightly than OR, so you need the parentheses around the parameters in order to give the ORs (or comma series) precedence. Just as you would have to use parentheses in this mathematical expression to make the addition get executed before the multiplication: 4 * (5 + 1). You'd get a different result if you left the parentheses out because 4 * 5 would be computed first and then 1 added (without being multiplied by 4 first).
What would be equivalent to type:(lexicon, encyclopedia, dictionary) would be if you repeated the type: filter for each of the terms:
type:lexicon OR type:encyclopedia OR type:dictionary
If you leave the type: off the latter terms, and omit the parentheses, the effect will be as KS4J has explained.
Thanks. Fully user error. [:)]
