Arturo Bernal commented on JSPWIKI-1321:
----------------------------------------
Pull request: https://github.com/apache/jspwiki/pull/575
A term of the name field with a * between other characters is also looked for
inside the words of the name and its parts in order in different words, so
name:blog*26 and name:entry*26* find Weblog_blogentry_021126_1; a term that
only ends in * still starts at the word. The relevance is scaled so that the
best result is 100. Three new tests in SearchManagerTest fail on the code of
pull request 543 and pass with the change; SearchManagerTest has 16 tests and
all pass. Not run: the whole test suite, the cost of terms with an inner * on a
large index, and the contents field.
> Wildcards in the middle of a search term do not match inside the words of a
> page name, and the relevance goes above 100

> Follow-up of JSPWIKI-501 (pull request 543), from the review of Ulf Dittmer.
> For a page named Weblog_blogentry_021126_1, the provider indexes in the field
> name the tokens weblog, blogentry_021126_1, weblog, blogentry, 021126 and 1
> (measured with ClassicAnalyzer on the text the provider builds for that
> field). A wildcard term is matched inside one token. Measured on an in-memory
> index with seven page names, with the behaviour of master and of the branch
> of pull request 543:
> * name:blog*26 finds nothing
> * name:entry*26* finds nothing
> * name:man* finds only Man_Page, not Human_Page or Woman_Page
> The reviewer expects the first two to find the page, and said that
> name:blog*26 finding nothing while name:blog*26* finds pages is unexpected.
> A second point from the same review: the relevance of a result is the Lucene
> score multiplied by 100 with no maximum, so values above 100 appear (108 and
> 255 were measured on the branch of pull request 543). The reviewer suggested
> scaling it to 0-100 or leaving it out.
> Not measured yet: the effect on searches in the page contents, and the cost
> of terms that begin with a wildcard.
