NCBI Entrez ESearch
===================

Responds to a text query with the list of matching UIDs in a given database
(for later use in ESummary, EFetch or ELink), along with the term translations
of the query.

Example Queries
---------------

Search in PubMed with the term cancer for abstracts that have an Entrez date
within the last 60 days:

+----------------------+-------------+
| Parameter            | Value       |
+======================+=============+
| NCBI Database to Use | PubMed      |
+----------------------+-------------+
| Term                 | Cancer      |
+----------------------+-------------+
| Datetype             | Entrez Date |
+----------------------+-------------+
| In past N Days       | 60          |
+----------------------+-------------+

Search PubMed Central for free full text articles containing the query stem cells:

+----------------------+--------------------------------------+
| Parameter            | Value                                |
+======================+======================================+
| NCBI Database to Use | PubMedCentral                        |
+----------------------+--------------------------------------+
| Term                 | Stem Cells AND free fulltext[filter] |
+----------------------+--------------------------------------+

Search in Nucleotide for all tRNAs:

+----------------------+--------------------------------------+
| Parameter            | Value                                |
+======================+======================================+
| NCBI Database to Use | Nucleotide                           |
+----------------------+--------------------------------------+
| Term                 | biomol trna[prop]                    |
+----------------------+--------------------------------------+

Search in Protein for a molecular weight range:

+----------------------+--------------------------------------+
| Parameter            | Value                                |
+======================+======================================+
| NCBI Database to Use | Protein                              |
+----------------------+--------------------------------------+
| Term                 | 70000:90000[molecular weight]        |
+----------------------+--------------------------------------+
