# INSPIRE-HEP [INSPIRE-HEP](https://inspirehep.net/?ln=en) is an open access digital library for the field of high energy physics ([Wikipedia](https://en.wikipedia.org/wiki/INSPIRE-HEP)). To fetch entries from INSPIRE-HEP, choose **Search → Web search**, and the search interface will appear in the side pane. Select **INSPIRE** in the dropdown menu. To start a search, enter the words of your query, and press Enter or the **Fetch** button. The results are displayed in the [import inspection window](/v4/import-export.md). In case an error occurs, it is shown in a popup. ## Query syntax The INSPIRE-HEP search function merely passes your search queries onto the INSPIRE-HEP web search, so you should build your queries in the same way, except omitting the *find* or *fin* command. This help page will only give a brief introduction to the search queries. More extensive help on searching INSPIRE-HEP can be found on the page . Your query can be composed of several parts, combined using *and* and *or* as logical operators. Each part is composed of a letter or word indicating the type of field to search, followed by a space and the text to search for. The following list shows some of the field indicators that can be used: * *a* or *author*: search author names * *t* or *title*: search in title * *j*: journal. Here either the common abbreviation or the 5 letter CODEN abbreviation for a journal can be used. Volume and page can also be included, separated by commas. For instance, *j Phys. Rev.,D54,1* looks in the journal Phys. Rev., volume D54, page 1. * *k*: search in keywords Example queries: * *a smith and a jones*: search for references with authors "smith" and "jones" * *a smith or a jones*: search for references with either author "smith" or author "jones" * *a smith and not t processor*: search for author "smith" and omit references with "processor" in the title --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.jabref.org/v4/finding-sorting-and-cleaning-entries/import-using-online-bibliographic-database/inspire.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
