Query mode syntax
Amplified supports traditional boolean logic alongside AI searching. To get access this feature, please contact your account manager or email us at support@amplified.ai.
Query mode operators
Proximity operators support up to 9 words (i.e. W9). We are in the process of increasing this limit.
Multi-word phrases such as "metal oxide" must be wrapped in quotation marks.
Wildcards cannot be used in combination with proximity operators. Amplified automatically handles truncation, plurals, and basic word variations. However Amplified cannot do this when wildcards are used. Accordingly, wildcards should be used sparingly.
Syntax guide
| Name | Description | Example | Type | Comment |
|---|---|---|---|---|
| Boolean operators | Basic boolean search operators | AND OR NOT | Search logic | |
| Advanced text operators | Wildcards and proximity searching for text searching | W5 * ? | Search logic | Use * for multi-character wildcards Use ? for single-character wildcards For proximity search use W with the number of words ex. W5 Note: for non-roman alphabets like Japanese, Korean, and Chinese the proximity operator will look within N characters rather than words |
| Nested queries | Nesting fields and logic for complex queries | TAC=(rocket AND engine AND (nitrogen OR hydrogen)) | Search logic | Be careful with overly complex nesting though as it can become difficult to follow and read |
| T=() | Title | T=(rocket) | Text | |
| A=() | Abstract | A=(rocket AND engine) | Text | |
| C=() | Claims | C=(fuel W3 thrust) | Text | |
| D=() | Description | D=(light* OR hyperspace) | Text | |
| TACD=() | Full text | TACD=(rocket OR engine) | Text | |
| TAC=() | Title or abstract or claims | TAC=(fuel OR thrust*) | Text | |
| IPC=() | IPC code | IPC=(A61F2/00) | Class | Codes before / such as A61 or A61F2 will automatically include all children. Codes after / such as A61F2/00 will only return exact matches. Append +all to include children ex. A61F2/00+all. |
| CPC=() | CPC code | CPC=(A61F2/00 OR B62J1/00) | Class | |
| GRANT=() | GRANT=(yes) | Legal status | ||
| ALIVE=() | ALIVE=(yes) | Legal status | ||
| EPRD=() | Earliest priority date in family | EPRD=20120501:20201231 | Date | Use : to specify a date range |
| EPD=() | Earliest publication date in family | EPD<=20201231 | Date | |
| CC=() | Country code (publishing authority) | CC=(US OR JP) | Country and publication codes | |
| ALL_AN=() | All assignees | ALL_AN=(Toyota) ALL_AN=("General Motors") | Names | |
| INV=() | Inventor name | INV=(Nikola Tesla) | Names | |
| S# | Previous search string | S1 AND S3 NOT S4 | Search string |
