We have 2 records with title 'horses'. with minwordlen=3, a count of title like 'horse' returns 0. count of title like 'horses' returns 2.

With a minwordlen=4, both counts return 2.

I am using TSQL with the default settings for suffixproc (on) and suffix list.

We can not set the minwordlen to 4 because we also want the words "dog" and "dogs" to show up in the same manner.

Should we be setting the minwordlen dynamically - depending on the size of the word?

What is your suffix list? You may also need to change the default suffix removal setting defsuffrm.

default suffix list - i am using tsql to get the counts. default defsuffrm.

When using vortex for the same, the defsuffrm=0, suffix list is "'", "s", "es".

You could add "se" to the suffix list. Though it could cause the occasional extra hit. Such as "treats" matching "treatise" with defsuffrm on. With defsuffrm off I doubt it would hurt at all.

Then how come it is working with minwordlen=4?

I have tried looking in the documentation, can you explain how does suffix proc work? I understand that the word is reduced to its stripped form based on minwordlen and suffix list. is that the word you enter as search word, or all words indexed?

What logic will help me decide what to include in the suffix list? In other words why wpuld adding "se" work?

Thanks.

Suffix rules apply to both query terms and text terms.
defsuffrm=0
minwordlen 4, sufs s es:
horses -> hors
horse -> horse (defsuffrm=1 -> hors)
minwordlen 3, sufs s es:
horses -> hors -> hor
horse -> horse (defsuffrm=1 -> hors)
minwordlen 4, sufs s es se:
horses -> hors
horse -> horse (defsuffrm=1 -> hors)
minwordlen 3, sufs s es se:
horses -> hors -> hor
horse -> hor
