Help - Searching

There are two ways to search our site. You can search:

  • the entire CCOHS site using the search box in the main navigation bar, or
  • across databases (chemical, bibliographic, legislation, MSDSs, etc.) and additional resources (OSH Answers, IPCS INCHEM, etc.). Advanced Search options are also provided.

Use the Quick Reference table below as a guide to searching our service.

Tip:     Use parentheses to make the search precise. If AND and OR operators are used without parentheses, the AND operation will occur first followed by OR operations. See Additional Ways to Refine Your Search for search examples using parentheses.


Search Hints & Tips

  • Searching for words automatically finds all forms of the words (as illustrated above). To avoid this "stemming" use quotes around the word.
  • When searching using multiple words, words are automatically combined together using the And operator (automatically Anded) in order to narrow your search. A search for welding fumes will find all forms of the word welding and the word fumes. To search for an exact phrase such as welding fumes, use quotes, e.g. "welding fumes".
  • If your search finds too many hits, try to use words that are very unique and specific. In our databases, avoid words such as "safety" or "health" as they appear in many records. Also, if your word is too general, such as "solvent" or "paint", you get a long list of search hits.
  • The words AND, OR, and NOT are always treated as search operators unless they are enclosed in double quotation marks, e.g. as in a search for health “and” safety, or “health and safety”.
  • In bibliographic collections such as OSH References, it is important to try a variety of synonymous terms to ensure greater results, i.e. RSI <OR> RMI <OR> "Carpal Tunnel".
  • Use parentheses to make the search precise. If AND and OR operators are used without parentheses, the AND operation will occur first followed by OR operations. See Additional Ways to Refine Your Search for search examples using parentheses.
  • If searching using CAS Registry Numbers, please note that some databases do not include CAS numbers, e.g. HSELINE (part of the OSH References collection).
  • Searching is case in-sensitive in all databases. Therefore:
  • In OSH References, if searching for the proper name of an author make sure to use the <CASE> operator followed by quotation marks, e.g. <CASE> "White" will find White but not white. Or, you can search for "White" <IN> Author.
  • In MSDS/FTSS, a search using either shell or SHELL will find both Shell and SHELL.
  • When using words or phrases with punctuation, e.g. apostrophy ('), ampersand (&), or periods, enclose them in quotation marks. See the examples in the Quick Reference above.
  • For product names, be sure your spelling is accurate. If in doubt, use the wildcard features:
    • a search for ?lean will find clean and klean
    • a search for gas* will find gas and gasoline.

Additional Ways to Refine Your Search

You can further refine your search or do a more precise search using these operators:
Search using Example(s) Finds all records with:
NEAR fire <NEAR> storage these words near each other
(the closer the words are in the record, the higher the ranking)
NEAR/#
(where # is up to 1000)
waste <NEAR/10> disposal these words within 10 words of each other
Sentence
(words in same sentence)
nausea <SENTENCE> rash nausea and rash in the same sentence
Paragraph
(words in same paragraph)
mould <PARAGRAPH> schools mould and schools in the same paragraph
Typo & Spelling*
(up to 2 typos)
<TYPO> fetoxisity either fetoxisity or fetoxicity
Parentheses (nuclear OR radioactive) AND program

either nuclear or radioactive, that also contain program

((nuclear OR radioactive) AND program) AND air either nuclear or radioactive, that also contain program and air
(Loctite OR Henkel) AND adhesive either Lockite or Henkel, that also contain adhesive

Use parentheses to make the search precise. If AND and OR operators are used without parentheses, the AND operation will occur first followed by OR operations.

Tip*:    Searches using the TYPO operator automatically find the US and UK spelling of most words, e.g. find sulfur and the UK spelling sulphur as well as spelling variations such as labeling and labelling.

Advanced Search Page -- to execute a precise search:

Using the Advanced Search page, you can:

  • build your search step-by-step using the boxes at the top of the Advanced Search page,
    or
  • type your query statement, including all appropriate syntax, in the Query box.

Each database/collection has an Advanced Search page which allows you to search in the specific fields for that database/collection. Click on the drop down button next to All Fields and select the field, e.g. Title, you wish to search. Frequently searched fields are provided in the drop down list.

While viewing a database record, you can find out the appropriate search names of all fields. Turn on the Field Help from the toolbar and click on the ? help symbol next to the field in any database record. You can now view the field description and field name to be used for searching (e.g. CASRegistryNumber).

Tip:   For a complete list of database fields, while viewing a database record turn on the Field Help from the toolbar and click on the ? help symbol next to the field in any database record. You can now view the field name and its description, from the complete list of fields for the database. You can easily print this list, by clicking in the field help window, right-clicking and then selecting Print.
