Keywords
Search |
| |
|
Users can enter a single keyword
in the query box (e.g., [Potato]), OES will search for
information that contains the word "Potato" and display search
results in the web page.
|
| |
| |
|
Users can
enter multiple
keywords in the query box, OES
will assign a score to each keyword by comparing the frequency
and location of each keyword, and generate proper results.
Keyword scores differ based on keyword frequency and where
those keywords are located in the article.
| |
|
The earlier those
keywords appear in the article, the higher the
score. |
| |
‧ |
An article will be given a higher
score with keyword that appears more frequently in an
article. |
| |
‧ |
An article will be given a higher
score when keywords in the article are located closer to
one another. |
Consequently, when the user enters
keywords [Couch Potato], OES will search for information that
contains both "Couch" and "Potato", and generate the search
results based on the above scoring criteria.
|
| |
Note
| 1. |
Because of the search performance
concern, OES will ignore specific word, such as
「a」and「of」. |
| 2. |
The queries OES provided are
case-insensitive. |
|
|
Phrases
Search |
| |
To conduct a phrase search,
simply place quotation marks around two or more words, OES
will search for documents containing an exact sentence or
phrase specified by the user.
When the user enters search strings ["Couch
Potato"], OES will only search for
information that contains the exact phrase "Couch Potato".
Constraints on phrase search are as follow: |
| |
|
Double quotes must be in half-width
characters |

This option can be used in combination
with the Boolean Query, with an exception that no Boolean
Operator can be included inside double quotes |
