Apart from knowing how to compile lucene (including the javacc code
generation) you should only need to change

<DEFAULT> TOKEN : {
  <AND:       ("AND" | "&&") >
| <OR:        ("OR" | "||") >
| <NOT:       ("NOT" | "!") >

to
<DEFAULT> TOKEN : {
  <AND:       ("AND" | "<insert your version of and here>" | "&&") >
| <OR:        ("OR" | "<insert your version of or here>" | "||") >
| <NOT:       ("NOT" | "<insert your version of not here>" | "!") >

in jakarta-lucene/src/java/org/apache/lucene/queryParser/QueryParser.jj=


Replacing the operators before query might be hard to do, if you want
to handle cases like =BB"a AND b" OR c=AB, which is a query for a=20
phrase "a AND b" or the token c, correctly.
