Hi
How to search for Solr special characters like '(' and '&'?
I am trying to execute searches for "products" in my Solr (3.6.1) index, based
on the "categories" to which these products belong.
The categories are stored in a multistring field for the products, and are
hierarchical, and are fed to the index like:
A
A|B
A|B|C
So this product would actually belong to category named "C", which is a child
of "B", which is a child of !"A".
I am able to execute queries for simple category names like this (eg.
fq=categories_string:A|B|C).
But some categories have Solr special characters in their names, like: "D (E &
F)"
(Real example: "Power supplies (Battery and Solar)").
A query like fq=categories_string:A|B|D (E & F) simply fails.
But even if I try
fq=categories_string:A|B|D%20\(E%20%26amp%3B%20F\)
(where I try to escape the special characters) does not find the products in
this category, and actually finds other unrelated categories.
What am I doing wrong?
Thanks,
Peter
