Find the Most Effective Search Terms Using Rank in PASCAL?
TOPIC: Produced by the Institut de l'Information Scientifique et Technique (INIST) of the French National Research Council (CNRS), PASCAL (File 144) provides access to the world's scientific and technical literature and includes about 450,000 new citations per year. Available on Dialog since 1973, PASCAL corresponds to the print publication Bibliographie internationale (previously Bulletin signaletique).
The key to targeted searching in PASCAL lies in a combination of keyword searching and using a Dialog specialized command to ferret out appropriate English-language descriptors. Most current records contain English (ED), French (FD) and Spanish (SD) descriptor fields. Searching with /DE retrieves descriptors in any language. However, you can use English-language descriptors by searching in the /ED field. Descriptors are indexed as individual words that you search using proximity connectors or as phrases (e.g., SELECT ULTRASONIC IMAGING/ED).
Likewise, titles of the original documents and any translations of the titles appear in the Title (/TI) field. Titles of documents originally published in English are indexed in the English Title (/ET) field. Most records include an English translation of the original title. Except for stop words, all words in the English Title field are searchable as single words using proximity operators with the /ET suffix.
Related databases include Inspec® (File 2), BioEngineering Abstracts (File 136*), SciSearch®: A Cited Reference Science Database (File 34) and Ei Compendex® (File 8).
In this example you will use keyword terms from the English descriptor and title fields; then you will use the RANK command to pinpoint effective English indexed terms for a search on robotic surgery used on cardiac patients.

HOW TO...
1. BEGIN File 144 to search PASCAL.
2. SELECT terms for the first concept in the English Descriptor (/ED) and the English Title (/ET) fields. The comma acts as OR.
3. SELECT the second concept in the same fields and combine with Search set 1 (S1). |
 |
4. RANK the descriptor field. The RANK command performs statistical analysis on retrieved records.
In this case, we want to know which descriptor terms appeared most in the 89 records in Set 2. We also want to gain insight on ways to structure the search.
5. Check the box(s) of the term(s) you wish to search and click the Search button. Two terms that stand out are robotics and cardio-vascular disease. Check one of them and remember the other, because we want to AND the terms rather than OR them.
Then click the Search button. |
 |
6. Dialog automatically searches the selected RANK term(s) and creates a search set (S3).
7. Combine Set 3 with robotics in the /DE field. (You can even narrow robotics to the English Descriptor field (/ED) if you wish.) Each record retrieved must have both the first descriptor and the second.
8. DISPLAY SETS (DS) to review your search history. |
 |
9. To ensure including keywords along with the indexed terms, OR the keyword set (S2) with the Descriptors set (S4).
10. Use database LIMIT options to restrict retrieval to original documents in English and a publication year range. The colon ORs the years in the range. This is an optional step.
11. TYPE a few records in Format 8 to browse titles and descriptors and check for relevancy. |
 |
Notice that in addition to English Descriptors PASCAL indexes Broad Descriptors (/BT). Cardiovascular disease is a Broad Descriptor term. That is why it is important to combine keywords with indexed terminology in PASCAL.

12. Click on record links to display the full records. Alternatively you can enter a TYPE command (e.g., TYPE s6/9/1-2,5).
Notice the Dialog eLink icon displayed at the top of the record. Searchers who have taken advantage of Dialog’s free eLinks service and have had their accounts enabled for eLinks can click the publisher link and go directly to their electronic journal subscriptions. They save lots of time by starting off with a precision Dialog search to get to the relevant fulltext documents they need on biotechnology topics.
Note: Portions of the record are omitted.
