Help Search

Check spelling: make sure your search terms are spelled correctly. Use multiple words: Using multiple words will return more refined results than a single word.
Example: pH combined electrode better than electrode

Use similar words: The more similar words you use in a search, the more relevant your results will be.
Example: titrator titration

Use appropriate capitalization: Capitalize proper nouns, and remember that lower-case words will match any case.
Example: pH will match pH but not phototrode, ph will match pH and phototrode.

Use quotation marks: Use quotation marks to find words which must appear adjacent to each other.
Example: "pH electrode" will match combined pH electrode and glass ph electrode but not reference electrode.

Use plus (+) or minus (-): Use a plus sign when your search term or phrase must appear in the search results. Use a minus sign to indicate undesirable term(s). The plus sign tells the search engine that a certain word or phrase is required in the search results, and a minus sign indicates that a word or phrase must be absent in the search results. Leave no spaces between the plus or minus sign and the term.
For instance, searching for +electrode -pH will find only the pages containing the word electrode without the word pH.

Use wildcards : Wildcard searches can expand the number of matches for a particular request. The * character is used as the wildcard character.
For instance, searching for titr* will find the words titration, titrator, titrators, titrant, and any other word that starts with titr.
Searching for *ectro* will find the words electrode, electrochemical, electrochemistry, spectroscopy and any other word that contains ectro anywhere in the word.
