Query & search

This guide walks through querying & searching registries. To understand the links between objects that enable relational queries, see Organize datasets. To query datasets in storage, see Query tables in storage and Query arrays in storage .

Basics

Create a database object:

import lamindb as ln

db = ln.DB("laminlabs/lamindata")

Show code cell output Hide code cell output

→ connected lamindb: anonymous/docs

! database has module pertdb, configure it: lamin settings modules set bionty,pertdb

Get an overview

Return the most recent entries of the Artifact registry as a DataFrame:

db.Artifact.to_dataframe()

Show code cell output Hide code cell output

! truncated query result to limit=20 Artifact objects

Here is more background on search and examples for searching the cell type registry: How does search work?

Auto-completing can also be a good way of finding an object:

records = db.Record.lookup()
experiment_1 = records.exp_rna_001  # assuming a record named 'EXP-RNA-001' exists
experiment_1

Show code cell output Hide code cell output

Record(uid='HhKWgzjVW6cfnVep', is_type=False, name='EXP-RNA-001', description=None, reference=None, reference_type=None, extra_data=None, branch_id=1, created_on_id=1, space_id=1, created_by_id=2, type_id='15982', schema_id=None, run_id=None, created_at=2026-05-04 13:46:47 UTC, is_locked=False)

This works for any BaseSQLRecord class, e.g., also for plugin bionty:

cell_types = db.bionty.CellType.lookup()

Queries

By fields

Use filter() to query artifacts by fields, e.g., by suffix:

This returns a QuerySet with the objects that match the filter. You can filter a queryset:

qs = qs.filter(records=experiment_1)  # filter to artifacts annotated with a record
qs.to_dataframe()

To access the results in a queryset:

• to_dataframe(): A pandas DataFrame with each object in a row.

• one(): Exactly one object. Will raise an error if there is none. Is equivalent to the .get() method shown above.

• one_or_none(): Either one object or None if there is no query result.

You can also:

• use the QuerySet as an iterator

• get individual objects via qs[0], qs[1]

The SQLRecord classes (registries) in LaminDB are Django Models and any Django query works. Django has a double-under-score syntax to filter based on related tables. This syntax enables you to traverse several layers of relations and comparators.

For example, the following filter selects artifacts based on the users who ran the generating notebook. Under the hood, in the SQL database, it’s joining the artifact table with the user table.

db.Artifact.filter(created_by__handle__startswith="testuse").to_dataframe()

Another example would be querying datasets that measure a particular feature. For instance, which datasets measure expression of CD8A:

cd8a = db.bionty.Gene.get(symbol="CD8A")
# query for all schemas that contain CD8A
schemas_with_cd8a = db.Schema.filter(genes=cd8a)
# get all artifacts
db.Artifact.filter(schemas__in=schemas_with_cd8a).to_dataframe()

By features

The Feature registry indexes variables across datasets to enable querying by dimensions. Registry fields couldn’t scale to millions of dimensions as found in biology:

The Artifact, Record, and Run registries can be queried by feature expressions:

feature_type = db.Feature.get(name="mini_immuno")
perturbation = db.Feature.get(name="perturbation", type=feature_type)
temperature = db.Feature.get(name="temperature")
db.Artifact.filter(
    perturbation == "DMSO",
    temperature > 21,
).to_dataframe(include="features")

You can query for whether a dataset is annotated by a feature:

db.Artifact.filter(perturbation.is_null(False)).to_dataframe(include="features")

Cheat sheet: comparators

You can qualify the type of comparison in a query by using a comparator. Below is a list of the most important ones, but Django supports about two dozen field comparators field__comparator=value.
