# In many cases you are not interested in a specific structure, but you
# want a set of structures that fits your desired criteria.
# For this purpose the *RCSB* search API can be used.
# At first you have to create :class:`Query` object for the property you
# want to filter.
# The :func:`search()` method takes the :class:`Query` and returns a
# list of PDB IDs, which itself can be used as input for
# :func:`fetch()`.
# Likewise, :func:`count()` is used to count the number of matching
# PDB IDs.

# This was a simple search for the occurrence of the search term in any
# field.
# You can also search for a value in a specific field with a
# :class:`FieldQuery`.
# A complete list of the available fields and its supported operators
# is documented
# `on this page <https://search.rcsb.org/search-attributes.html>`_.
# Query for 'lacA' gene
