Hoss Man commented on SOLR-3287:
--------------------------------
I don't have a "great" suggestion for dealing with this. Fundementally it
comes down to a conflict between trying to make the field types used by the
example fields general and generic enough to be useful for any languages so
people can re-use them, vs having fields in the example that let us show off
some features that aren't neccessarily things all users will want in all of
their text fields if they copy the schema.
we could use copyField to create "_en" versions of all these fields, but this
type of solution has also lead to confusion/problems in the past, with people
leaving those copyFields in the shchema.xml when they copy it, and winding up
with indexes that are twice as big as they need to be.
My best suggestions are:
* For the search links in #1::
** leave the verbage as is, but maybe put this line in bold: *Go ahead and edit
the schema.xml under the solr/example/solr/conf directory, and change the type
for fields text and features from text_general to text_en_splitting* ... i
would also suggest changing it to: *Go ahead and edit the schema.xml under the
solr/example/solr/conf directory to use type="text_en_splitting" for the fields
"text" and "features"*
** include a <pre> box showing an example of what the <field/> declarations
will look like in XML if the user makes these changes
** i think we should also change the example queries so they aren't actually
links -- just show the query syntax. my thinking being that this will act as a
metnal cue that these are examples of valid queries, but they don't work "out
of the box"
* For the analysis.jsp link in #2: i think we should switch from using the
"name=name" and "name=text" params to using "type=text_en" (with a tweak in
verbage to make it clear what the URLs are showing) so these work even if the
user doesn't edit the schema.
Anyone have any better ideas?

>
> I just audited the tutorial on the 3x branch to ensure everything would work
> for the 3.6 release, and ran into a two sections where things were very
> confusing and seemed broken to me (even as a solr expert)
> https://svn.apache.org/repos/asf/lucene/dev/branches/branch_3x/solr/core/src/java/doc-files/tutorial.html
> 1) "Text Analysis" of the 5 queries in this section, only the "pixima"
> example works (power-shot matches documents but not the ones the tutorial
> suggests it should, and for different reasons). The lead in para does
> explain that you have to edit your schema.xml in order for these links to
> work -- but it's confusing, and i honestly read it 3 times before i realized
> what it was saying (the first two times i thought it was saying that
> _because_ the content is in english, english specific field types are used,
> and you can change those to text_general if you don't use english)
> Bottom line: the links are confusing since they don't work "out of the box"
> with the simple commands shown so far
> {panel}
> If you know your textual content is English, as is the case for the example
> documents in this tutorial, and you'd like to apply English-specific stemming
> and stop word removal, as well as split compound words, you can use the
> text_en_splitting fieldType instead. Go ahead and edit the schema.xml under
> the solr/example/solr/conf directory, and change the type for fields text and
> features from text_general to text_en_splitting. Restart the server and then
> re-post all of the documents, and then these queries will show the
> English-specific transformations:
> * A search for power-shot matches PowerShot, and adata matches A-DATA due to
> the use of WordDelimiterFilter and LowerCaseFilter.
> * A search for features:recharging matches Rechargeable due to stemming with
> the EnglishPorterFilter.
> * A search for "1 gigabyte" matches things with GB, and the misspelled pixima
> matches Pixma due to use of a SynonymFilter.

> 2) "Analysis Debugging"
> Likewise, all of the analysis.jsp example URLs attempt to show off how
> various features work, but the fields used don't demonstrate the analysis
> being discussed unless the user has edited the schema as discussed in the
> previous section
> {panel}
> This shows how "Canon Power-Shot SD500" would be indexed as a value in the
> name field. Each row of the table shows the resulting tokens after having
> passed through the next TokenFilter in the analyzer for the name field.
> Notice how both powershot and power, shot are indexed. Tokens generated at
> the same position are shown in the same column, in this case shot and
> powershot.
> Selecting verbose output will show more details, such as the name of each
> analyzer component in the chain, token positions, and the start and end
> positions of the token in the original text.
> Selecting highlight matches when both index and query values are provided
> will take the resulting terms from the query value and highlight all matches
> in the index value analysis.
> Here is an example of stemming and stop-words at work.
