Boolean
WIKI supports Boolean search methodology. The boolean full-text search capability supports the following operators:

+
A leading plus sign indicates that this word must be present in each row that is returned.

-
A leading minus sign indicates that this word must not be present in any of the rows that are returned.

Note: The - operator acts only to exclude rows that are otherwise matched by other search terms. Thus, a boolean-mode search that contains only terms preceded by - returns an empty result. It does not return “all rows except those containing any of the excluded terms.”

(no operator)

By default (when neither + nor - is specified) the word is optional, but the rows that contain it are rated higher. This mimics the behavior of MATCH() ... AGAINST() without the IN BOOLEAN MODE modifier.

> <
These two operators are used to change a word's contribution to the relevance value that is assigned to a row. The > operator increases the contribution and the < operator decreases it. See the example following this list.

( )
Parentheses group words into subexpressions. Parenthesized groups can be nested.

~
A leading tilde acts as a negation operator, causing the word's contribution to the row's relevance to be negative. This is useful for marking “noise” words. A row containing such a word is rated lower than others, but is not excluded altogether, as it would be with the - operator.

*
The asterisk serves as the truncation (or wildcard) operator. Unlike the other operators, it should be appended to the word to be affected. Words match if they begin with the word preceding the * operator.

If a word is specified with the truncation operator, it is not stripped from a boolean query, even if it is too short (as determined from the ft_min_word_len setting) or a stopword. This occurs because the word is not seen as too short or a stopword, but as a prefix that must be present in the document in the form of a word that begins with the prefix. Suppose that ft_min_word_len=4. Then a search for '+word +the*' will likely return fewer rows than a search for '+word +the':

The former query remains as is and requires both word and the* (a word starting with the) to be present in the document.

The latter query is transformed to +word (requiring only word to be present). the is both too short and a stopword, and either condition is enough to cause it to be ignored.

"
A phrase that is enclosed within double quote (“"”) characters matches only rows that contain the phrase literally, as it was typed. The full-text engine splits the phrase into words and performs a search in the FULLTEXT index for the words. Nonword characters need not be matched exactly: Phrase searching requires only that matches contain exactly the same words as the phrase and in the same order. For example, "test phrase" matches "test, phrase".

If the phrase contains no words that are in the index, the result is empty. For example, if all words are either stopwords or shorter than the minimum length of indexed words, the result is empty.

EXAMPLES
The following examples demonstrate some search strings that use boolean full-text operators:

'apple banana'
Find rows that contain at least one of the two words.

'+apple +juice'
Find rows that contain both words.

'+apple macintosh'
Find rows that contain the word “apple”, but rank rows higher if they also contain “macintosh”.

'+apple -macintosh'
Find rows that contain the word “apple” but not “macintosh”.

'+apple ~macintosh'
Find rows that contain the word “apple”, but if the row also contains the word “macintosh”, rate it lower than if row does not. This is “softer” than a search for '+apple -macintosh', for which the presence of “macintosh” causes the row not to be returned at all.

'+apple +(>turnover Find rows that contain the words “apple” and “turnover”, or “apple” and “strudel” (in any order), but rank “apple turnover” higher than “apple strudel”.

'apple*'
Find rows that contain words such as “apple”, “apples”, “applesauce”, or “applet”.

'"some words"'
Find rows that contain the exact phrase “some words” (for example, rows that contain “some words of wisdom” but not “some noise words”). Note that the “"” characters that enclose the phrase are operator characters that delimit the phrase. They are not the quotation marks that enclose the search string itself.

US Symposium Keynote: Brian Polagye (University of Washington)

2012-07-24 | From Administrator

This keynote speech was presented at the First Annual INORE North American Symposium, June 17-21, 2012 at the Massachusetts Maritime Academy.

Brian Polagye is a professor at the University of Washington, and is one of the original INOREans.

Biography
My research focuses on sustainable electricity generation from the kinetic energy in moving water, particularly tidal current energy.

Characterizing Tidal Energy Resources
Maximizing power generation at a tidal energy site requires information about the hydrokinetic resource at spatial scales ranging from 10 cm to 10 km and time scales ranging from fractions of a second to years. This understanding is gained by developing new site survey techniques, models to predict deterministic and stochastic components of the tidal resource, and methodologies to analyze collected data. Information is used by site developers to estimate long-term power generation potential and device developers to estimate design loads.

Tidal Energy Sustainability
A renewable resource is a necessary, but not sufficient, condition for sustainable power generation. Research in this area seeks to improve the sustainability of tidal energy by improving our understanding of environmental effects, in order to influence engineering decisions related to turbine design. This is done through a combination of field studies, instrumentation development, and modeling. Specific areas of interest are in the acoustic effects of tidal energy, interactions between marine life and tidal turbines at close range, and the consequences of energy removal on estuarine systems.

Instrumentation Micropower
Long-term monitoring of tidal energy sites is constrained by the power available to operate instrumentation. This limits the type of instrumentation that can be deployed and the maximum duration of observations. Given that the average resource intensity within a meter of the seabed generally exceeds 500 W/m2 at tidal energy sites, micropower generators with swept areas on the order of 1 m2 incorporated into instrumentation packages could significantly enhance monitoring capabilities. We are developing a self-contained, micro-scale tidal generation system capable of meeting a continuous load of 20 W via a small, rechargeable battery bank.
