======  Result Advanced Filter Search Syntax ======

When utilizing BioGRID ORCS advanced filters, you have the option of applying simple boolean options to perform more advanced searches. First each individual field acts as an **AND** search. So, for instance, if you search for //cancer// in the Cell Type field and //Sapiens// in the organism field, you will return rows containing **BOTH** cancer in Cell Type **AND** sapiens in organism.

Within an individual field, however, you can search for multiple terms at the same time using a simplified boolean syntax. The following are the available options:

  - **BOOLEAN OR** : You can search within a single field for one term or another team simultaneously using the keyword **OR**. For example: **Lung** OR **Breast**. This will return any result containing the term Lung OR the term Breast in your specified field. 
  - **BOOLEAN AND** : You can search within a single field for one term and another team simultaneously using the keyword **AND**. For example: **Lung** AND **Cancer**. This will return any result containing both the term Lung AND the term Cancer in your specified field.
  - **EXACT PHRASE** : You can search for an exact phrase using double quotes. For example, if you search for <nowiki>"Lung Cancer"</nowiki> in the cell type field, it will only match if the exact cell type <nowiki>"Lung Cancer"</nowiki> exists. This will not match the phrase **lung cancer cell line**. This is useful for matching phrases that may be sub-components of larger phrases. For example, you may want to search for <nowiki>"CAS9"</nowiki> in the enzyme field if you want only the enzyme CAS9 to show up and not the enzyme dCas9-KRAB. Searching for CAS9 without quotes would return both matches.
  - **GROUPING** : You can group together phrases using round brackets for more complex style queries. For example: Cancer AND (Lung OR Breast). Phrases in brackets are executed first and then matches with those outside the brackets. 
  - **WILDCARD MATCHING** : You can optionally include wildcard searches as well. For instance, if you want to match all identifiers starting with NF OR MED you can simply search for ** NF* OR MED* **. Wildcard searches do not work when the * is placed inside a set of double quotes. 
==== Examples ====
  * Find all lung cancer cell types: **<nowiki>Lung Cancer</nowiki>**
  * Find all lung or breast cancer cell types: **<nowiki>Cancer AND (lung or breast)</nowiki>**
  * Find all Toxin Exposure and Drug Exposure experiments: **<nowiki>"Toxin Exposure" OR "Drug Exposure"</nowiki>**
  * Find all Knockout or Activation Libraries: **<nowiki>"CRISPRn" OR "CRISPRa"</nowiki>**
  * Find all screens using the Bagel or Mageck statistical analysis method: **<nowiki>"BAGEL" OR "MAGECK"</nowiki>**
  * Find all gene names starting with STE or CLN or UPS: **<nowiki>STE* OR CLN* OR UPS*</nowiki>**
