# Xapian Search Results not Quite as Expected
## Tags
* type: bug
* assigned: arun, fredm
* priority: medium
* status:
* keywords: xapian, search
## Description
The following is a list of failing examples of search, with notes on what I expected.
### Querying by Name
=> https://genenetwork.org/gsearch?type=phenotype&terms=name%3ABXD_24417 with `name:BXD_24417`
=> https://genenetwork.org/gsearch?type=phenotype&terms=species%3Amouse+AND+BXD_24417 with `BXD_24417`
=> https://genenetwork.org/gsearch?type=phenotype&terms=species%3Amouse+AND+24417 with `24417`
To verify that the trait exists, here is
=> https://genenetwork.org/show_trait?trait_id=24417&dataset=BXDPublish the trait page
That also means we cannot do an inverse search, where we say something like
```
species:mouse NOT BXD_24417
```
Here is
=>https://github.com/genenetwork/genenetwork3/blob/98e9726405df3cce81356534335259a446b0c458/scripts/index-genenetwork#L215-L216 some related code
relating to the indexing of the data for search.
### `NOT` Operator not Working Right
=>https://genenetwork.org/gsearch?type=phenotype&terms=species%3Amouse+AND+author%3Ahager+NOT+%22BXD+Published%22 Searching by dataset name
works as expected, but should you want to, say, filter out one of the authors, with something like
=>https://genenetwork.org/gsearch?type=phenotype&terms=species%3Amouse+AND+author%3Ahager+NOT+%28%22BXD+Published%22+AND+author%3A%22Lu+L%22%29 this search,
you do not get the expected results.
Changing the search to
=>http://genenetwork.org/gsearch?type=phenotype&terms=species%3Amouse+AND+author%3Ahager+AND+%28NOT+author%3A%22Lu+L%22%29+AND+%28NOT+%22BXD+Published%22%29 more clearly bracketed queries
leads to an outright exception: This should probably be handled.
=>https://genenetwork.org/gsearch?type=phenotype&terms=species%3Amouse+AND+author%3Ahager+AND+NOT+author%3A%22Lu+L%22 Here is another example
of the `NOT` operator acting a little weird: note that phenotypes with "Lu L" as an author still show up.
