Use multiple words

Multiple-word queries will return more refined results than single-word ones will. For example, IRA account application will return more relevant results than just application. (Keep in mind that relevant results are returned even if they don't contain all query terms.)

Example: IRA account application

Use similar words

The more similar words you use in a search, the more relevant your results will be.

Example: safe secure privacy security

Use quotation marks

Use quotation marks to find words that must appear adjacent to each other, for example, "Education IRA" Without quotes, the search results will include the words education and ira, but not necessarily in that order (i.e., the words may appear anywhere, and in any order, within the document).

Example: "Education IRA"

Check spelling

The search engine will attempt to find words that sound similar to your search terms, but it's always best to try to spell the search terms correctly.

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.

Note: A phrase must be contained within quotation marks. Leave no spaces between the plus or minus sign and the term.

Example: +"David Herro" -"International Small Cap"

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 wh* will find the words what, why, when, and any other word that starts with wh.
Searching for *her* will find the words here, whether, together, gathering, and any other word that contains her anywhere in the word.

Wildcards may be combined with the plus (+) and minus (-) modifiers, quotes for phrases, as well as the field search specifiers.
+wh* -se*ch will find all pages that have a word that starts with wh and does not contain a word that starts with se and ends with ch.
"wh* are" will find the phrases where are, what are, why are, etc.

Examples:
 "Clyde Mc*"
 "prospe*"

Use field searches

Field searches allow you to create specific searches for words that appear in a specific part of a document. A field search can be performed on body text (body:), title text (title:), meta key words (keys:) or URL (url:). The field name should be in lower-case and immediately followed by a colon. There should be no spaces between the colon and the search term.

Note: The field searches can only be followed by a word or phrase. Phrases must be contained within quotation marks.

Examples:
 title:about
 keys:prospectus
 body:"quarterly report"
url:help
