+### Ingredient Querying Language
+
+An ingredient can refer one exact item or items that matches the conditions.
+
+To specify single exact item:
+
+    ID IS item@basegame:1
+
+To specify using tags:
+
+    TAG HASALLOF a_tag,b_tag,c_tag OR TAG IS s_tag
+    TAG IS one_tag
+    TAG HASALLOF a_tag,b_tag
+
+The query can have one or more terms. The terms are always either one of:
+
+    TERM  OPERATOR  TERM
+    TAG_LITERAL
+
+Since "TAG" is a valid term to operate against, said word can frequently appear for complex queries.
