Excellent, it didn't seem clear but if the items are showing up on the crawl logs then that's a good sign.
Can you find those items in any dedicated search pages?
Do you get different behaviour with normal users and Site Collection administrator users?
Are list searches working in other lists in the same site collection?
I start wondering if I stating my problem correctly.
I have a sharepoint website containing various wikis, lists (ie table web part), files, diary.
On several pages I have search textboxes : either dedicated search page (SearchCenter), or part of a list web part.
Content crawling is activated on :
1) All sharepoint site (containing wikis, lists web parts, docs etc)
2) "Private sites" to populate profiles
3) Network shares.
If I start a query on a dedicated search page (ie https://mysite/SearchCenter/Pages/), I get results : persons, documents, page contents from wiki etc.
If I go to a list page (simple tabular data entered via a form) and use the webpart's integrated search box, I get no restult.
I don't know if I'm using the right terms, this sharepoint was inherited from a company we bought so I did not participated in its installation.
Thanks.
