You can issue a delete command to Solr by simply doing a GET (or POST)
to http://localhost:8983/solr/update?stream.body=%3Cdelete%3E%3Cid%3ESOMEID%3C/id%3E%3C/delete%3Eete%3E%3Cquery%3Esome:query%3C/query%3E%3C/delete%3E&commit=true
(replace SOMEID with whatever unique id you want, or switch to use the
delete-by-query)
In turn, is it possible to copy all of the XML elements from said
item and
place them in a document somewhere locally once it's been removed?
You could do a /select?q=id:SOMEID&fl=* and get all stored field
values (note you'll lose any unstored values) and stash those results
off however you like.
Finally, there is one default search field. How do you search on
multiple
different fields in PHP?
Use the dismax parser. /select?
q=whatever&defType=dismax&qf=field1+field2
See the wiki docs on dismax for more details and list of other
parameters.
If I wanted to search by all of the fields indexed, is that easy to
code?
You could list all fields in the qf field of dismax.
Another option is to copyField all fields you want searchable into a
single field and search that single field.
What changes do I need to make in the XML schema?
To use dismax, no changes to schema are needed (necessarily).
But you may want to add copyField's to schema.xml to collect all field
text into a single field for default field searchability.
