Example 1: Searching Within an Example Document
Example 2: Combining Multiple Full-Text Search Fields
Full-Text Search Results of Search A
Full-Text Search Results of Search B
Example 1: Searching Within an Example Document
Operator | Full-Text Search Query | Hit | Explanation |
AND | ◎ | Both the words "antibody" and "polypeptide" appear in the example document. | |
- | The word "DNA" does not appear in the example document. | ||
◎ | The word "polypeptide" appears in the example document, while the negated word "DNA" does not appear in the example document. | ||
OR |
◎ | Both the words "antibody" and "polypeptide" appear in the example document. | |
◎ | One of the words ("polypeptide") appears in the example document. | ||
RNA OR DNA | - | Neither one of the words "RNA" nor "DNA" appears in the example document. | |
NEAR |
◎ | The words "isolated" and "position" appear within 5 word jumps of each other in the example document. | |
- | The words "isolated" and "position" do not appear within 2 word jumps of each other in the example document. | ||
◎ | The words "isolated" and "position" appear within exactly 4 word jumps of each other in the example document. | ||
◎ | The space-separated words "position" and "polypeptide" appear adjacent to each other in the example document. Spaces between words are interpreted as the proximity operator "SEQ1". | ||
SEQ |
◎ | The words "isolated" and "position" appear within up to 5 word jumps of each other in this order in the example document. | |
- | The words "position" and "isolated" appear within exactly 4 word jumps of each other in the example document but not in this order. | ||
Wildcard |
◎ | The word "polypeptide" appears in the example document. The asterisk wildcard can replace "poly". | |
◎ | The words "HVR-H1", "HVR-H2", etc. appear in the example document. The double question mark wildcard can replace "H1", "H2", etc. | ||
X3? | - | The example document contains no word that begins with "X3" and ends with exactly one additional character. | |
◎ | The word "chain" appears in the example document. The word "chains" would also result in a hit. |
Example 2: Combining Multiple Full-Text Search Fields
The PatentSight full-text search browses through patent documents but it returns patent families as the search results. Moreover, the document segments (title, abstract, claims, description) selected in each full-text search field are connected by OR operators. This becomes apparent when comparing the results of the following two sample searches A and B:
Search A | TC=(steel AND alloy) |
Search B | TC=(steel) AND TC=(alloy) |
Full-Text Search Results of Search A
Search A returns patent families that include at least one document as family member that contains both "steel" and "alloy" in the title and/or in the claims. This means that the same family member must meet both conditions: It must contain both "steel" and "alloy" in at least one of the segments selected.
Example Patent Family | Hit |
Patent family 1, where the US document contains "steel" and "alloy" in the title. | ◎ |
Patent family 2, where the JP document contains "steel" in the title and "alloy" in the claims. | ◎ |
Patent family 3, where the KR document contains "steel" in the claims and the DE document contains "alloy" in the claims. | - |
Patent family 4, where the FR document contains "steel" in the title and the CN document contains "alloy" in the claims. | - |
Full-Text Search Results of Search B
Search B returns patent families that include at least one document as family member that contains "steel" in its title or claims and at least one document that contains "alloy" in its title or claims. This means that different members of the same family can meet both conditions individually.
Example Patent Family | Hit |
Patent family 1, where the US document contains "steel" and "alloy" in the title. | ◎ |
Patent family 2, where the JP document contains "steel" in the title and "alloy" in the claims. | ◎ |
Patent family 3, where the KR document contains "steel" in its claims and the DE document contains "alloy" in the claims. | ◎ |
Patent family 4, where the FR document contains "steel" in the title and the CN document contains "alloy" in the claims. | ◎ |
Consequently, Search B returns more search results than Search A.
