[Fields and Commands](https://knowledgebase.ensembleip.com/migration/quartet/inputs?hsLang=en#fields-and-commands) # Search Fields ## The search fields define what is to be searched. Using search fields, the user can focus their search to different text fields, limit the search to specific classification areas, and define specific date ranges for the search query. Search fields can be defined using the Fielded search interface and via search commands in the Command Line. There are 6 different types of search fields, each containing different types of content. The 6 types of search fields are: - [Text Fields](https://knowledgebase.ensembleip.com/migration/quartet/search-fields#TextFields) - [Number Fields](https://knowledgebase.ensembleip.com/migration/quartet/search-fields#NumberFields) - [Date Fields](https://knowledgebase.ensembleip.com/migration/quartet/search-fields#DateFields) - [Country & Kind Codes Fields](https://knowledgebase.ensembleip.com/migration/quartet/search-fields#CKCFields) - [Classification Fields](https://knowledgebase.ensembleip.com/migration/quartet/search-fields#ClassFields) - [Party Fields](https://knowledgebase.ensembleip.com/migration/quartet/search-fields#PartyFields) - [Legal Status Fields](https://knowledgebase.ensembleip.com/migration/quartet/search-fields#LegalStat)   When using the command line, search fields are specified by the user and written on the left-hand side of the query. Search fields of the same type can be combined together using forward slash ( / ). **TI/AB/CLM=(personal 2W computer)** is the same as  **TI=(personal 2W computer) OR AB=(personal 2W computer) OR CLM=(personal 2W computer)**  ### Text Fields | **TI** | Title | **TI**=(personal 2W computer) | | --- | --- | --- | | **AB** | Abstract | **AB**=flow? | | **DES** | Description | **DES**=(laptop OR tablet OR notebook) | | **CLM** | Claims | **CLM**=(plane 3W (engine OR motor)) | | **FT** | Full Text FT is equivalent to **TI/AB/DES/CLM** | **FT**=(short\_cut AND project) | | **TA** | Title and Abstract TA is equivalent to **TI/AB** | **TA**=translation | | **TAC** | Title, Abstract, and Claims TAC is equivalent to **TI/AB/CLM** | **TAC**=(GPU OR processor) | | *none* | If no field is given and the user has not specified a default field in their settings, then the default field is **FT**. | (personal 2W computer) | ### Number Fields | **PNUM** | Publication Number | **PNUM**=(US2001023123A1 OR KR20049312??) | | --- | --- | --- | | **ANUM** | Application Number | **ANUM**=(US60423099) | | **FNUM** | Family Number (DOCDB Family Number) | **FNUM**=(3467725 OR 987542) | ### Date Fields Date fields are searched using =, \<, \>, =\<, and =\> followed by the desired date. Greater than ( \> ) and less than (\< ) exclude the entered date, while greater than or equal to ( =\> ) and less than or equal to ( =\< ) include the entered date. | **PUBD** | Publication Date | **PUBD**=2002-01-28 *(Results include documents with a publication date of January 10, 2002)* | | --- | --- | --- | | **APPD** | Application Date | **APPD**\<2001-03 *(Results include documents with an application date before March 31, 2001)* | | **PRID** | Priority Date | **PRID=\<**2003 *(Results include documents with a priority date on or before December 31, 2003)* | Date formats accepted are YYYY, YYYY-MM, and YYYY-MM-DD When searching for a range, a colon ( : )can be inserted between two dates in any of the accepted formats.  Ex. 2003:2008 *includes documents with a publication date in the range of years from 2003-01-01 to 2008-12-31)* ### Country & Kind Codes Fields | **CC** | Country Code | **CC=**(CN OR FR) | | --- | --- | --- | | **KC** | Kind Code | **KC**=(B1) | | **CKC** | Country code & kind code | **CKC**=(CNB? OR JPB2) | A table of country names and country codes can be found in the [country code table](https://knowledgebase.ensembleip.com/quartet/country-code-table?hsLang=en).   ### Classification Fields | **IPC** | IPC Classification Codes | **IPC**=(C07K16/28 OR C07K16/42) | | --- | --- | --- | | **CPC** | CPC Classification Codes | **CPC**=(C07K16/2812 OR C07K16/4275) | | **USPC** | United States Patent Classification Codes | **USPC**=(340/2.2) | | **JPFI** | Japanese File Index Codes | **JPFI**=(G06F7/535\_520 OR H04B7/26\_109@M) | | **JPFT** | Japanese F-Term Codes | **JPFT**=(5B016\_FA05) | In addition to using asterisk ( \* ) for truncating a classification code, the plus sign ( + ) can also be used to search a classification code and all subordinate subgroups. Classification systems can be combined in one command if a code is common to multiple systems. Here are some examples: - CPC/IPC=G06F1/03 - IPC/CPC/JPFI=G06F1/03   ### Party Fields | **PA** | Applicants and assignees | **PA**='Intel Corp⁎' | | --- | --- | --- | | **IN** | Inventors | **IN**=(Jane 2D Doe) |   ### Legal Status Fields | **LGL** | Legal status Can take both short and long forms of legal statuses (see table below) | **LGL**=status **LGL**=(Boolean expression of status) | | --- | --- | --- | #### Searchable Legal Status Terms The legal status terms are searchable in both a long and short form. | Long form | Short form | | --- | --- | | alive | | | dead | | | pending | pend | | granted | grant | | lapsed | laps | | recentlylapsed | rlaps | | longlapsed | llaps | | revoked | rev | | expired | exp |     - [Getting started](https://knowledgebase.ensembleip.com/migration/quartet/getting-started?hsLang=en#main-content) - [Workspaces and Search projects](https://knowledgebase.ensembleip.com/migration/quartet/getting-started?hsLang=en#workspaces-and-search-projects) - [Crafting Search Strings](https://knowledgebase.ensembleip.com/migration/quartet/getting-started?hsLang=en#crafting-search-strings) - [Ways to search](https://knowledgebase.ensembleip.com/migration/quartet/getting-started?hsLang=en#ways-to-search) - [Seeing your results](https://knowledgebase.ensembleip.com/migration/quartet/getting-started?hsLang=en#seeing-your-results) - [Search Guide](https://knowledgebase.ensembleip.com/migration/quartet/search-guide?hsLang=en#main-content) - [Interface](https://knowledgebase.ensembleip.com/migration/quartet/search-guide?hsLang=en#interface) - [Methods of Searching](https://knowledgebase.ensembleip.com/migration/quartet/search-guide?hsLang=en#methods-of-searching) - [Reviewing References](https://knowledgebase.ensembleip.com/migration/quartet/search-guide?hsLang=en#reviewing-references) - [Other](https://knowledgebase.ensembleip.com/migration/quartet/search-guide?hsLang=en#other) - [Patent Coverage](https://knowledgebase.ensembleip.com/migration/quartet/patent-coverage?hsLang=en) - [Inputs](https://knowledgebase.ensembleip.com/migration/quartet/inputs?hsLang=en#main-content) - [Operators](https://knowledgebase.ensembleip.com/migration/quartet/inputs?hsLang=en#operators) - [Fields and Commands](https://knowledgebase.ensembleip.com/migration/quartet/inputs?hsLang=en#fields-and-commands) - [Special Characters](https://knowledgebase.ensembleip.com/migration/quartet/inputs?hsLang=en#special-characters) - [Alerts](https://knowledgebase.ensembleip.com/migration/quartet/alerts?hsLang=en) - [Settings](https://knowledgebase.ensembleip.com/migration/quartet/settings?hsLang=en#main-content) - [Customization](https://knowledgebase.ensembleip.com/migration/quartet/settings?hsLang=en#customization) - [Videos & Webinars](https://knowledgebase.ensembleip.com/migration/quartet/videos-webinars?hsLang=en#main-content) - [Full Overview of How to Use Quartet](https://knowledgebase.ensembleip.com/migration/quartet/videos-webinars?hsLang=en#full-overview-of-how-to-use-quartet) - [ProTip Videos](https://knowledgebase.ensembleip.com/migration/quartet/videos-webinars?hsLang=en#protip-videos) - [Webinars](https://knowledgebase.ensembleip.com/migration/quartet/videos-webinars?hsLang=en#webinars) - Home - Products - Pricing - Blog - Company [![Chill listening crop-3](https://knowledgebase.ensembleip.com/hs-fs/hubfs/EnsembleIP%20logo%20(light)-2.png?width=132&height=24&name=EnsembleIP%20logo%20(light)-2.png "Chill listening crop-3")](https://knowledgebase.ensembleip.com/?hsLang=en) Copyright © 2026, Ensemble IP LLC
