您可以使用搜索字段进一步细化结果：

by feed ID: f:123 or multiple feed IDs (or): f:123,234,345
by author: author:name or author:‘composed name’
by title: intitle:keyword or intitle:‘composed keyword’
by URL: inurl:keyword or inurl:‘composed keyword’

by date of discovery, using the ISO 8601 time interval format: date:
From a specific day, or month, or year:
date:2014-03-30
date:2014-03 or date:201403
date:2014
From a specific time of a given day:
date:2014-05-30T13
date:2014-05-30T13:30
Between two given dates:
date:2014-02/2014-04
date:2014-02–2014-04
date:2014-02/04
date:2014-02-03/05
date:2014-02-03T22:00/22:15
date:2014-02-03T22:00/15
After a given date:
date:2014-03/
Before a given date:
date:/2014-03
For a specific duration after a given date:
date:2014-03/P1W
For a specific duration before a given date:
date:P1W/2014-05-25T23:59:59
For the past duration before now (the trailing slash is optional):
date:P1Y/ or date:P1Y (past year)
date:P2M/ (past two months)
date:P3W/ (past three weeks)
date:P4D/ (past four days)
date:PT5H/ (past five hours)
date:PT30M/ (past thirty minutes)
date:PT90S/ (past ninety seconds)
date:P1DT1H/ (past one day and one hour)
by date of publication, using the same format: pubdate:
by custom label ID L:12 or multiple label IDs: L:12,13,14 or with any label: L:*
by custom label name label:label, label:“my label” or any label name from a list (or): labels:“my label,my other label”
by several label names (and): label:“my label” label:“my other label”
by entry (article) ID: e:1639310674957894 or multiple entry IDs (or): e:1639310674957894,1639310674957893
by user query (saved search) name: search:myQuery, search:“My query” or saved search ID: S:3
internally, those references are replaced by the corresponding user query in the search expression
Be careful not to enter a space between the operator and the search value.

Some operators can be used negatively, to exclude articles, with the same syntax as above, but prefixed by a ! or -: !f:234, -author:name, -intitle:keyword, -inurl:keyword, -#tag, !keyword, !date:2019, !date:P1W, !pubdate:P3d/.

It is also possible to combine keywords to create a more precise filter. For example, you can enter multiple instances of f:, author:, intitle:, inurl:, #, and free-text.

Combining several search criteria implies a logical and, but the keyword OR can be used to combine several search criteria with a logical or instead: author:Dupont OR author:Dupond

You don’t have to do anything special to combine multiple negative operators. Writing !intitle:‘thing1’ !intitle:‘thing2’ implies AND, see above. For more pointers on how AND and OR interact with negation, see this GitHub comment. Additional reading: De Morgan’s laws.

Finally, parentheses may be used to express more complex queries, with basic negation support:

(author:Alice OR intitle:hello) (author:Bob OR intitle:world)
(author:Alice intitle:hello) OR (author:Bob intitle:world)
!((author:Alice intitle:hello) OR (author:Bob intitle:world))
(author:Alice intitle:hello) !(author:Bob intitle:world)
!(S:1 OR S:2)
ℹ️ If you need to search for a parenthesis, it needs to be escaped like ( or )
