Advanced arXiv Search Queries

The AI Research Assistant accepts arXiv search syntax when creating a research database. More precise queries can improve the relevance of papers retrieved during ingestion.

Search Fields

arXiv supports searching specific metadata fields.

Field	Description	Example
ti:	Title	ti:"machine learning"
abs:	Abstract	abs:"machine learning"
au:	Author	au:"Geoffrey Hinton"
cat:	arXiv category	cat:cs.LG

For example:

ti:"Julia"

searches for papers containing Julia in the title.

Boolean Operators

Search expressions can be combined using AND and OR.

AND

Use AND when both conditions should be present:

ti:"Julia" AND abs:"machine learning"

OR

Use OR when either condition may be present:

ti:"Julia" OR abs:"Julia"

Combining Fields

More precise searches can combine multiple fields and Boolean operators:

(ti:"Julia" OR abs:"Julia") AND
(ti:"machine learning" OR abs:"machine learning")

This searches for papers that mention Julia and machine learning in either the title or abstract.

You can also restrict results to a specific arXiv category:

(ti:"Julia" OR abs:"Julia") AND cat:cs.LG

Choosing a Query

A broad query such as:

machine learning

may retrieve many loosely related papers.

When building a focused research database, prefer field-specific queries that describe the topic as precisely as possible:

(ti:"hyperspectral" OR abs:"hyperspectral") AND
(ti:"subspace clustering" OR abs:"subspace clustering")

More restrictive queries generally improve relevance, but may return fewer papers.
