Using Lens for prior arts search, how do we survey for “A” + “B or C” + “D”. This is case for someone to have the composition A and “B or C”, and “D”.
Answer: The best place to write more advanced searches is in the main search bar. You can use a Structured Search to create an initial query and then edit it from there. You can achieve your example query a number of ways:
- (A AND B) OR (C AND D)
- && is an alias for AND and || is an alias for OR which can help visually separate the logic from the query terms and also make queries slightly shorter: (A && B) || (C && D)
- Because AND is the default logical operator, this is query is equivalent: (A B) OR (C D)
- To search a specific field in the index (or fields) use: field:(A AND B) OR field:(C AND D)
- For example, querying on titles: title:(fish AND bowl) OR title:(horse AND cart)
- A more complex example: (title:(fish AND bowl) OR title:(dog AND bowl)) AND abstract:food AND jurisdiction:(US OR KR)
- Which is equivalent to these queries: (title:(fish && bowl) || title:(dog && bowl)) && abstract:food && jurisdiction:(US || KR) (title:(fish bowl) || title:(dog bowl)) abstract:food jurisdiction:(US || KR)

What is a simple family? What is difference between “simple family size” vs. “extended family size”?
Answer: For more information on patent family types, check our support page at https://www.lens.org/
support/help-resources/ document-views/family-info- tab/
When I organize the search results according to “simple family”, the search results list is less than what appears to be the entire family? Why?
Answer: sorting by “Simple Family” means sorting by Simple Family size and not by “Simple Family wherein the documents are listed in family order”. A change in the label may remove the confusion.
If I don’t want to do structured search, but do a free form search, where can I find the field codes? For example, Applicant, assignee, terms in claim? How do you narrow down search results using “and” “or” “not”? It appears that the code for “and” is &&, what about “or” or “not”?
Answer: Please check the support page that lists the search field names and describes the search language here: https://www.lens.org/sup
I searched for 2014/0295923 and did not get any results, but when I searched by author, I was able to see the document. How can I search by publication number?
Answer: If you search the lens using 2014/0295923 or 20140295923, you will not get any results. However, if you search for 20140295923 or US20140295923 or US20140295923A1 or US_20140295923_A1, you would be able to see the requested patent document. An alternative approach is also available if we use advanced search option and specify that you are searching by publication number (pub_num:20140295923)
I would like to search for the keywords leishmani* AND diagnos* in the title OR abstract and retrieve among these documents the ones which contain A61K* OR C12N* as IPC OR as CPC. I would like to know if I can use the following search string on this search: title:(leishmani* AND diagnos*) || abstract:(leishmani* AND diagnos*) && classification_cpc:(A61K* OR C12N*) || classification_ipcr:(A61K* OR C12N*)
Answer: Add extra grouping brackets to the two main clauses:
(title:(leishmani* diagnos*) OR abstract:(leishmani* diagnos*)) AND (classification_cpc:(A61K* OR C12N*) OR classification_ipcr:(A61K* OR C12N*))
I’m not finding a solid description of the proximity operator(s) used on The LENS. I’m seeing variously that the tilde is used, or perhaps it is NEAR/n. On another system, I have used ADJ. Please help by providing the operators.
Answer: Essentially you use the tilde, “~”, symbol at the end of a phrase to specify a word distance. The search “foo bar”~4 searches for ‘foo’ and ‘bar’ within 4 words from each other. Exact matches are proximity zero, and word transpositions (bar foo) are proximity 1.
Question: “I am getting confused with using the lucene syntax. I first assumed I didn’t need to use parenthesis as the ‘structured search’ fields were providing this.
Answer: The structured search provides a way to build some relatively simple queries. For advanced queries with nested clauses you’ll need to compose them manually. See our lucene syntax support page for further info on lucene search syntax: https://www.lens.org/s
When I search for ‘energy generator’ in the abstract in a single field or in separate query fields, I get 271555 hits. But when I search ‘energy’ in one field AND ‘generat*’ in another I only get 964 hits. I can see that it is the wild card that is causing this problem.
Answer: This is to do with search term stemming. Please check the wildcard section in the search syntax support page above to explain this behaviour.
I wanted to search for “Electroactive polymer”~4 AND “generat*” AND “Energy” but am getting zero hits regardless of whether I use parenthesis or not. Can you advise of the correct input?
Answer: Turn stemming off. Searches are case insensitive, no quotes around wildcard term generat* as the wildcard will lose effect, no quotes needed for single non-phrase term “Energy”. “electroactive polymer”~4 AND generat* AND energy Also, AND is the default boolean operator so (with stemming turned off) you could just use: “electroactive polymer”~4 generat* energy
I also wondered if it was possible to ‘refine’ within a stored collection using keywords? It seems after the initial search has been done refinement is only possible through selecting or deselecting fields. I would find it useful to apply keywords within a collection particularly since the keywords are highlighted in the text. I see the work around is to repeat the original search with additional keywords and/or use the browser ‘find in page’ function. One thing I really miss from the IPO system is being able to highlight different words within results using different colours – basically a multiple ‘find in page’.
Answer: If you ‘view’ a collection, you can then search within the collection using the search bar above the collection listing results (‘Refine your Search’) in addition to the selecting filters on the left.
How about a ‘multi-highlight’ functionality?
Answer: The ‘multi-highlight’ chrome add-in can be used to give you the same highlighter functionality as in EPODOC interface. https://chrome.google.com/
webstore/detail/multi- highlight/ pfgfgjlejbbpfmcfjhdmikihihddee ji . A Lens user recommended this feature as it works really well with Lens.
